Best explanation. Specially the orientation test part. No one on the KZbin had explained this easy and best way.

[@AnthonyJ350]

Thank you so much for the kind words!

[@ohokcool]

Agreed! It clears up specifically what the orientation affects, instead of just saying one orientation is right and the other is wrong. Just because there’s a better way to do something doesn’t mean people shouldn’t understand all the details. Foundational knowledge like this is what helps people understand more advanced things down the line.

[@daimlerfan9498]

I’m lost. I’m trying to do this with clearance lights on my truck.

[@UnreadyPlayer]

It's a good thing I caught your video before messing around with my car's fuse box. I really thought the taps were plug and play; the orientation is critical and must be stressed out. Thanks for sharing your knowledge, man! 🤙🤙

[@AnthonyJ350]

Glad you found the video helpful! 🙂

[@Spartan-Of-Truth]

Same issue for me. I’ll be adding the new fuse (along with the old as I just have the old one in) to the tap and see if my issue gets resolved.

[@gunningopher]

This is a good subject to bring up. When I first started using these, I didn't consider the functionality you describe and had to revisit some that I had put in my wife's Bronco and my truck. That being said, I don't' know what the manufacturer recommends and I'm no automotive EE, but I think what you recommend is not correct unless you can confirm that the fuse panel has a high enough rating in the panel. Certainly fuses are there to protect the wiring after the fuse, but the manufacturer has the BUS and wiring leading to the fuse with the load in mind as well. IMO the main circuit (original rating) fuse should protect the draw from both loads until you confirm that the entire run (before and after) can support both loads. This has the effect that sort of makes the add-on accessory subservient to the main load fuse. Yes this runs the risk of popping that fuse and cutting power to 2 accessories more often, but that keep the wiring safe, which is one of the main reasons you fuse before the wiring in the first place. The key is to pick the right load to tap into, an intermittent one that ideally isn't being used when the second load is active or that has a high start-up draw. A 'cigarette lighter' fuse position is a perfect choice. It has user controlled demand. Ultimately, I don't think it matters, since I don't think you should tap more than about 5A this way anyhow. High wattage transceivers (CB, ham, GMRS), off-road lights, air pumps, coolers and etc. should be run off a dedicated circuit from the battery, in my opinion. I've set up a bus for those before to minimize the battery connections.

[@AnthonyJ350]

That's why they're only suited for low amperage applications or just used as triggers.

[@shark_plissken]

i think i agree with you.. i would WANT my "aftermarket" device to trip off and not run if the fuse blew. It would indicate something is wrong. If i connected it the way suggested where constant power is going to it, something is off, and the source fuse blew, but i may not relaize it if its something small

[@who-dn5cl]

Thank you very much Anthony for the clear instructions and very useful practical demo. I am 70 and just decided to install my own dash cam |(for the first time)which requires permanent 12V supply .

[@snipermconeshot]

Just what I was looking for. I did assume correctly about the placement of the factory v aftermarket fuse because of the lead wire's placement, but watching your instructional video taught me how to confirm/test these taps/adapters. Thank you.

[@AnthonyJ350]

Glad it helped!

[@spelunkerd]

Those are good points. Traditional engineering aims to position fuses upstream of the wires they protect, but there is a practicality of how to protect the short stretch of wiring leading to the fuse. When those boxes are designed the engineers will not consider that somebody would tap a fuse and add more current. So, you take a small risk to upstream wiring when you add a second circuit in parallel. If you have add a 5 amp circuit to a 10 amp preexisting circuit, now the maximum upstream current is 15, not 10. I agree with your remark that putting fuses in series for branch circuits feels messy, but it does safely limit upstream current to what it was designed for, 10 in that example. Fortunately there is usually enough tolerance built into standards that the risk is low. Even so, I like your idea of a relay, which allows design of the heavy elements of the circuit directly from a source of power.

[@AnthonyJ350]

Thanks for the comment!

[@davidk7050]

I agree, it is safer to run all the current through the bottom fuse so you protect your car wiring from being overloaded. That is the purpose of having the fuse.

[@luispires5399]

Excellent explanation with the whole picture including the meter on continuity,I’m an electrician (commercial) not automotive. Thanks so much for making the video. I posted a written explanation before with a hand drawn diagram but you took it to another level. Especially explaining Not to tap off critical task functions.❤

[@joeldoxtator9804]

Thank's. This was a good explanation of what to expect when tapping a fuse. I bought a new set of headlights that requires a fuse tap for the DRL's and no tap was included for the harness. Now I know what I need and how to use it.

This video was amazing, it help me figure out exactly what my problem was by explaining the fuse adapters needing to be plugged in a certain way to get power.

[@AnthonyJ350]

Thank you for watching!

[@holdenhewitt251]

In other words, if you first test only the new fuse (in the slot closest to the wire), you can determine the correct orientation based whether or not your accessory is getting power, without needing to check for continuity. Great video!

Hi, great video and amazing explanation just one question if you could answer please 🙏 So for the fuse adapter when you plug in the car fuse and then have to put another fuse on top which fuse do you have to put on top ?

[@AnthonyJ350]

How come you're adding another fuse on top?

[@hawkeye7435]

The fuse that put on top is your new additional fuse where you supposed to run your additional new circuit. The fuse in the bottom is the old factory existing fuse.🙂

[@MarzNet256]

Cool. I actually picked these up to use as a tap on an Amp Buddy to get voltage in addition to current readings on a pico scope (won't be drawing any Amps with it). I could use a piercing probe on the Amp Buddy loop but this seems like a better solution.

Real important point is that the Fuse Tap pin furthest from the Fuse Tap cable is where active power should come in. So in the example shown initially inside the fuse box, with power to the right side of the fuse, that means the fuse tap cable should run to the left. Often people will mistakenly orient the fuse tap where it best fits.

[@AnthonyJ350]

Thanks for the comment!

Thank you for these tips. My problems solved. Just need to find out which fuses I can use to power up my aftermarket powered windows and seats. Any ideas? Once again your tips is very well appreciated.

[@AnthonyJ350]

That type if install you'll need to run a thick wire to the battery and fuse it at the battery for your relays.

[@SoaringAguila1969]

@ Thank you for your response. With that setup would I still get a continuous power? Not like other accessories(cigarette lighter or radio) it’s off when the car is off. And that the set up I would like for the powered seats and windows. Trying to avoid the battery from getting drained. Btw I do have relays but not sure if that will work . Do you have realy recommendations for my applications. Thank you

[@shehzad555]

Hey mate. Thank you for this video it was broken down nicely. I understand that the tap will need to be positioned correctly so that it piggybacks the constant power from the fuse box. However, where you lost me is in terms of the difference in amp between the fuse that came with the fuse tap and the normal fuse from the car. What should be the difference.

[@AnthonyJ350]

I try to always have the aftermarket fuse a smaller value than the factory one.

[@عبدالرحمناسكندر-ص3ر]

Does the after market fuse’s amber has to be strictly less than the original circuit fuse, or it can be equal to it also? And which one is better, the original fuse’ amber equal to the aftermarket one, or it is bigger than it?

[@AnthonyJ350]

Preferably smaller. If you have to pull amperage, use the fuse tap to control a relay that is fused and hooked up to the battery.

[@gnt256]

when i check the source side of the spade is the car on aux or off?

[@davidnajera483]

7:59 at this time you said to pick and ignition fuse to tap into but a couple seconds later you said not to tap into ignition. Which one did you mean if you don’t mind? Also what about empty fuse ports? Would we be able to use those spots by just adding a fuse in there? If not how come?

[@joshuachristabanera7133]

This is a very very educational video, thank you very much for this. But I need some clarification. In my Pajero Sport, I have a dedicated RELAY SLOT and FUSE SLOT for heated seat (20A) and headlamp washer (20A) which at the moment are empties because i dont have these features. Now I plan to install additional LED DRL's or aux lights (max 8A) that would stay ON the entire time while engine is running. Can I safely use those empty relay and fuse slots? Not needing anymore extra relay for those aux lights?

I think so. Heated seats pull a lot and you're attaching a device well under the rating of the wiring. As long as it's fused correctly and you pick a good ground.

Can you use this method to create an always hot cigarette socket?

[@hectorheras2158]

So to sum it up, if you did it correctly you can test if you did it correctly by disconnecting one of the fuses the other one should stay on, if you connect it back and disconnect the other fuse the other one should stay on?
