How to wire a Motogadget M-Unit

[@wallstreetjibaro]

Best explanation of the M-unit on YT definitely

[@artifactvsc7557]

Classic Octane does it again! Probably the best M Unit explanation on YT. Great work dude!

[@ClassicOctane]

Thanks!

[@londoncaferacer5816]

Definitely the best explanation I've seen on an m-unit video.

[@weeverob]

wow, terrific job on explaning this device. Motogadget should put this video on their website. i just came from there having read their installation manual. made no sense to me, felt like i needed to go back to school and get an electrical engineering degree. Thx Octane!

[@Typhlosion100]

Rob Weaver Motogadget fails to explain it clearly and other KZbinrs don’t go as in depth. +1 for Motogadget using this video on their website.

[@SuperCleetis]

Well now I’m gonna buy a m unit and re wire my bike. This makes life so much easier, thanks for the video man!!!

[@TheInsox]

Got myself a new base bike to build a new bobber. I was thinking about to put a m unit in and watched a few vids on YT but this one is the most clarifying one I have seen :)! Very helpful, so thanks :D!

[@stugixer57]

Clear and concise tutorial, I’m a machinist by trade but this is giving me the confidence to have a go on the XS650 I am building 👍

[@pjacksII]

Everyone's already said it but best M-Unit video on KZbin, great job!

[@michaelbell8590]

Dude! That was so freaking informative! Please, please, please would you make a video how to wire up everything to just start a bike and shut it off with an M Unit! I currently trying to figure that out. Haha

[@user-vp8dw9cz6q]

Michael Bell I’m getting into that now with my sportster bobber build did u ever find anything as clear and clean as this video with regard to tieing into the charging and ignition system ?

[@nuttop01]

great video the very best m-unit explained on youtube took me hours to sort mine out wish had seen this first

[@jids78]

OMG who disliked this video? it is very educational and deep on understanding motorcycle electrical. I love to buy this whole demo set to play with :) Classic Ocatne, can you make a vedio how to detect electrical problem with a multimeter? It is not necessary with the m.Unit but just for educational purpose. I have a Buell XB which has an electrical problem which power off when handle bar is turned and back on when turned back to its original position.

[@furnimaker]

I got an m-unit for my weird k-bike project, but haven't wired it up yet. I'm a hardware dude rather than an electrical guy, so wiring up my project has been something I've been looking forward to doing because I know I'm going to learn a lot. I'm still a ways off though. Looking forward to seeing how the wiring up of your bobber goes!

[@truth2500]

I can't wait to have this on my 73 z1. when I heard about this it blew my mind. Great video's.

[@jvsdibond1768]

thanks for taking the time to do this vid bro' , very clear and easy to understand delivery .

[@carlosgooglemaps94]

I know it’s an old video but it might help someone; to my knowledge you have the 30 amps fuse wrongly installed, the fuse should go on between the switch key and the M-unit, the switch key is what actually powers on the unit, the wire from the battery (positive) only powers the right side of the unit (outlets) only when it get the signal from the buttons (signals, light, brakes, etc.) and since the Unit has its own protection against shortcuts that might occur at the right side (positive side out) so a fuse on this side is useless

[@rickborland4118]

Well done!! Excellent explanation!!

[@TINKcustoms]

Watched a few m-unit install videos and this is by far the best. Thank you. Feel confident to get one myself and give it a go! Presumably regulator/rectifiers are not part of this unit and are wired as always independently?

[@sbkarmen]

Great video I'm doing an ultimate build but I'm having doubts about having the time to do this but I'm gonna have too

[@andrewritchie1699]

Excellent explanation. Very clear. I'm looking forward to fitting my mine under my cafe seat.

[@kultbotcustomshop3849]

Not sure if I told you this already but your a damn life saver lol

[@ryanjohnson6582]

Thanks for all that you do. This video covered how to power the gauge indicator lights for oil, neutral, and high beam but didn’t cover the turn signal indicator light. I’m trying to get it to light up with either indicator is on but ending up bridging the connection so all turn signals end up going off together. Do you have a recommended approach for this?

[@streitlucas]

Awesome tutorial man, really helpful

[@stevewright6333]

Looks like a good bit of kit.

[@94music94]

Awesome. Thanks for clarifying this.

[@lcrgarage3245]

Great video. Helped me decide to buy one for my next build, xs850.

[@TINKcustoms]

Forgot! Another question. Can you use lockable switches for headlight, ie separate for low/high beam?

[@johnblack1443]

GREAT video..well done and the best m-unit tutorial out there. Keep it up!

[@janzienkiewicz5295]

Hi there, so I’m just about to start to wire my 67 t120 . My question is ..... as it’s now 2022 is there something better or maybe cheaper on the market or ami best off following you using this 2017 M unit.? Thanks so much for this brilliant video so helpful 👍🏼

[@TrackSol]

Another idea for the kill switch would be to interrupt the lock ground input coming from the key. That way you dont have 12v on the handlebar

[@lvwrx]

great break down of the wiring!!

[@punkuk1979]

Looking to install one of these units in a Caterham Do you need relays for the lights and starter

[@guntherkuhn324]

Excellent excellent video! Thank you so much!!

[@alexhuber2965]

Question for you: it seems like the M-unit will work with any switch since you aren't using the moto gadget switches they sell. Do you see any problems of using a regular set of ignition/blinker/headlight that you can find on amazon? do you need to ensure the buttons are momentary?

[@josephbergin7017]

Can you use the m unit on a modern bike i.e. Suzuki b king 2008

[@josephbergin7017]

Question if I may . Currently building a street fighter. Japanese bike Suzuki. Trying to figure out something with the switch gear wiring. Have ordered momentry switches. The oem switch gear wiring harness , can the oem harness be wired to the momentary switches . As the standard loom all the wiring works as it should. Wondering if say I cut the oem switch gear could I then use the wiring to connect in the momentry switches Thanks for any information.

[@hugomolina.Realtor]

Thx for the Great video on the basic installation. How do you wire up the CDI or fuel pump ?

[@Typhlosion100]

Hugo Molina fuel pump would probably run through the distribution block

[@pete9834]

Great explanation m8! Thank you

[@joshfavela9439]

Great video !

[@evanjensen7662]

Do you have a link to that distribution block by chance?

[@person2984]

To be clear, installing this would mean ripping out your entire wiring harness (including fuses, relays, etc.) and running direct lines from all of your components to the M-Unit (and it will act as a fusebox/relay/etc. for all of them)?

[@ClassicOctane]

Correct, this is a solution to rewire the whole bike. I used it on my Triumph bobber to convert to a negative earth system. You only need one main power fuse and the rest is all handled internally in the M-unit. If you short something out you just power cycle the unit to reset it.

[@yl4970]

Hey, real great video, just like many others you made! Have a question about the M-Unit as only now I am seeing this for the first time. So, I do understand the value of this M-Unit when used/installed in old bikes that have been completely stripped off their wiring harness. But what value such an M-Unit provides to working bikes that have no problems with their wiring harness? Say I have a 2020 model bike that I want to add auxiliary lights to it. What would be a good reason to use the M-Unit for such case? In other words, it is not clear, to me, as to what are the use cases for using such a device and what are the scenarios that it is not recommend using such a device...Perhaps you can further clarify?

[@josephsano9760]

All new ignition module new new coil still can't get fire any thoughts using factory wiring

[@josephsano9760]

I need help I have a 86 sporster with m unit v.2 I didn't install wiring got messed up how can I get a wire for wire diagram for a harley

[@ianglaurie]

this is awesome - where did you get the extra distribution block?

[@gcrichlow17]

How do you setup the alarm on a kickstart bike?

[@lesjones7617]

Love all that!

[@robthomason1]

Super clear, concise video, man! I’ve looked everywhere though for one of those power and earth multiplier blocks! Where’s it from?

[@ClassicOctane]

amzn.to/2xCz3JD I used these cut in half.

[@jasonmcginn9515]

I'm guessing this eliminates the fuse box in all other little relays and such just to clarify

[@sokycraftcompany253]

This is a awesome review!!! ... Couple questions ? How is a starter relay wire goina fit in that tiny hole my wires like 8 gauge lol...im using a Icu box on a 2000 r6 would this m unit replace that ? So my igntion coils run to each other than to the ground and the ICU so i would just run them to the aux hole? Sorry I'm just a little confused .. I need to get this bike running ..lol

[@renechandomid2217]

excelente explicación, muchas gracias!!

[@donnakerfoot3028]

can you post a link to your wiring diagram

[@Typhlosion100]

So if I wanted to use the factory handle bar control buttons I could use them on this setup in place of the toggle switches correct?

[@spencerprewitt3534]

Quick question man, if you are using a unit like this on a cb550 per say, does this essentially eliminate the use of the original fuse box?

[@chrisbroadus3444]

Great explanation , well detailed. 👌 one question. How would I wire a reg rec to the m unit

[@jonivanart]

Great job! Lovin this unit!

[@650fan8]

Nice video, very informative! Do you still need to run a voltage regulator?

[@ClassicOctane]

Yes, I'm running a modern solid state voltage regulator.

[@craiggregory967]

Great video! Can the M unit be used with M switches on a 6 volt system?

[@tylerwoolley6215]

I have a question about the antigravity battery you show in this video. Is the 4 cell usually enough for a cafe build? I’m working on a 1980 Honda CM400T and I would much rather buy the 4 cell than the 8 cell, but I’m worried it’s too small.

[@ClassicOctane]

If you plan to use an electric start the 4 Cell is going to be a little too small. Kick start only you should be good.

[@crackedfingerz]

Where can I get the distribution box? I've been having trouble finding one online. Great crash course, by the way. Thanks!

[@BradleyWentzel]

Do you have to use the distribution block? If so, do you recommend one?

[@roberymcgoff1904]

No you don't he's just using it as a ground.Once your light or horn button is mounted its grounded through the frame. U can also run a single wire tail lite and m box can send for voltage when you tap the brake switches. The box can do alot more than he's showing you. Black Heart. Cycle

[@saltymotorworks4496]

Awesome explanation! We've used these on a few bikes, thinking about trying to use one on our 240Z track car build. Can you think of any reason offhand that it might not work?

[@ajscott3988]

How would you wire for the hazard signals with the m unit? I don't think you mentioned anything about a hazard switch unless I missed it.

[@ajscott3988]

would you just ground the hazard switch to the input of both turn signals at the same time?

[@ClassicOctane]

Yes, that's exactly what you would do. Ground one side of the switch and run the other side to both signal inputs. This is what the book says. "For starting the hazard light hold the push buttons for left and right turn signal for 2 seconds. If a turn light switch is used, the hazard light function can only be activated if an additional hazard light switch is activating both turn light inputs at the same time. The hazard light mode will stay active even if the main (ignition) switch is deactivated. "

[@ajscott3988]

So the m unit basically only replaces the wiring, fuses, and relays for the lighting and handlebar controls correct? I would still need to retain all the OE wiring for the tci and rectifier ?

[@increasedelevation3776]

Super helpful! Thank you

[@takeabow2774]

first of all great job explaining the wiring setup! You really did a great job clearing things up. However in the munit schematics i cant find the 30 amp fuse you put in there in the beginning. What is that for? I thought the munit has internal fuses? And next what is this black ground distribution thing? I think i didnt really understand the "ground" concept. Can't i just connect all the cables ground i need at the exact same place/screw that is somewhere on the bikes frame?

[@ClassicOctane]

The 30 amp main fuse isn't technically required but it's not a bad idea. I wanted a little more protection in the event of a short. All of the individual components are internally fused so you don't need anymore fuses. I used a ground distribution block in my headlight so that I didn't have 8+ wires running to the two grounding points on the unit. You can use the frame as well as long as you make sure the negative side of the battery has a good connection to the frame.

[@takeabow2774]

Thank you! Do you have a link for the specific block you used by any chance?

[@ClassicOctane]

All the parts I use are in the Amazon like in the description. www.amazon.com/shop/influencer-3f8085ce

[@tommylud4324]

Classic Octane just got a new m-unit. The manual says the fuse is mandatory. Max of 40A. Maybe it’s with the new units?

[@nicholasjheinz7461]

enjoyed the video!

[@vi3trascal]

amazing video! great information. Im getting ready to re do my wiring on my honda shadow chopped build and had a question. Would you happen to know where to wire up the ignition control module?

[@ClassicOctane]

Not sure without looking at a wiring diagram. I would assume it's just a key on power, ground, and the coil triggers in and out.

[@steveo8263]

Great video.... cheers

[@MM-mn2tu]

Wow! Well done! Where did you buy the button switch for operating the lights? Also, what keyed switch are you using? If this is an OEM switch , how is it wired? I have 4 wires coming from my OEM cb360. Thanks, keep the videos coming.

[@ClassicOctane]

It’s just a standard momentary switch. Same goes for the ignition switch it’s just a universal 3 position switch.

[@tnguyen-jf1pm]

would you link the red headlight button that you have in video please?

[@ClassicOctane]

It's just a universal button from Autozone if I remember correctly. I didn't actually use this button on the bike.

[@tnguyen-jf1pm]

Classic Octane I’m thinking about put it in a 3 button switch. It seems neater than toggle switch. But thank you

[@simpleone973]

Awesome videos! On a side note; do you have any suggestions on how to remove the seal on my shifter? 75' 550

[@ClassicOctane]

I have just used a pick in the past. It's kind of a pain.

[@_nader.essa_]

Great vid!

[@user-qt9ez5hl4k]

Nice video! I have a question on the fuses. Is the 30amp fuse you have at the battery line the only fuse you need to run?

[@ClassicOctane]

Yes, everything else is inside the m-unit. If something shorts out it will turn the LED on the unit on and when you cycle the key it will reset it.

[@tommylud4324]

What kind of 30A fuse holder do you use in this build?

[@ClassicOctane]

Just a universal one. Nothing special.

[@tommylud4324]

Classic Octane thought so. Just dummy checking my own stuff. Love your videos. And that wire diagram!! Awesome work sir

[@simpleone973]

Would you still need a starter solenoid with the unit?

[@ClassicOctane]

You still need the solenoid you would just use this to trigger it.

[@vishnusankar1693]

Yes

[@jamiewaterman9878]

Fantastic

[@youneedhost]

And how much this unit is?

[@taynemccloud8283]

Sorry I'm very stupid when it comes to this stuff. Do you not need fuses anymore with this?

[@ClassicOctane]

Just one main fuse but you don't need anything else.

[@SendingStache]

dope video my man!

[@bomcswine7985]

Hey i’m in the same boat as some when it comes to the instruction manual. I’ve been watching your video and it’s been such a help. i think i just hit a wall in my set up. I’m running the same set up as yours in the video. but hit a snag because my bike was running a lot of after market components with the stock harness. i just have a 1995 Honda XR600R that is an AC only, kickstart bike but was modified by the previous owner who added a baja kit, digital tachometer, battery, Reg/rect Is there anyway you could give me some guidance on the wiring? or work with me on a diagram?

[@gime8148]

Go to rivival cycles! He explains it better!

[@7AirCanuck7]

Best M-Unit vid wiring I’ve seen. I have a question for you. I am just about to re-wire my cafe that has an munit. Too many mechanics couldn’t figure out the “newfangled” wiring when a problem popped up and they’ve created a rats nest. Currently there is an issue (I didn’t wire it) where no matter what is selected, hi or lo, both wires are hot with voltage leading to the bulb. The low beam looks good but the hi beam is super dim. The hi beam indicator on the acewell is always on. In the bulb, both the low and hi filaments are illuminated regardless. The wiring seems to be set up properly as far as the munit is concerned. What might cause this?

[@ClassicOctane]

That's a tough one. Have you verified it's programed properly? Make use the headlight is setup for the type of switch you're running (push button or two position switch)

[@7AirCanuck7]

hey, yes, I made sure the handlebar configuration was correct on the programming side. I'm starting to think there must be a grounding issue somewhere... going to re-wire it this weekend hopefully. Pretty much guarantees I won't ride this bike this year... which I bought in August! Way more issues than anticipated

[@347chas]

Having problems wiring two position switch with 3 wires, spent several hours & no further from when i started.

[@JH-kj4id]

Thank you so much for the awesome explanation. One thing I noticed, the m-unit has built in circuit breakers, but you still had fuses inline with the headlight. Is that just because you haven't cleaned those up or are they still required!

[@ClassicOctane]

Those are just bullet connectors. That's the headlight from my Triumph so I didn't want to cut those wires. You don't need any fuses outside of the main 30A fuse from the battery to the unit.

[@mynameis890]

could you use this for a car?

[@ClassicOctane]

I was actually thinking about that for my Model A hotrod project when I get around to that. I don't think it would work for a more modern car as it doesn't have enough circuits to run everything (Fans, radio, A/C, heat, locks, windows, ETC)

[@mynameis890]

is there a limit to what can be run through the aux, amperage wise? or just run any other things that cant be ran through the m unit to a separate power distribution block that is switched, fused, and ran straight to the battery?

[@ClassicOctane]

my name is you could easily run a few relays off of the AUX output to run larger amp draw items.

[@viswanathaniyer2372]

good viedeo

[@mafosa8519]

Is it waterproof?

[@ClassicOctane]

No, I don't think so.

[@ajscott3988]

I have a couple questions and need a little help wiring my m unit. Do yall have an email or phone number to contact you at? Thanks.

[@ClassicOctane]

You can email me at [e-mail] or DM me on Instagram @ClassicOctane

[@ajscott3988]

Sent an email a couple days ago but no reply. Thanks anyways, I'll figure it out.

[@jeffersonsteeleflex8178]

I thought I could tackle wiring..... I was so wrong.

[@reaper20015]

I'm not digging the idea that when 1 $300 plus unit decides to take a crap, my whole bike won't work. Might be nice for a show bike or a limited use bike, but wouldn't trust it for my daily.

[@viswanathaniyer2372]

good viedeo
