Hey SCJ we enjoy watching all your vids. Keep them coming. Have ever considered using Racepak Smartwire for a PDM when wiring up your race car?

Yeah I feel the smartwire has it’s place. This car is pretty straight forward race car. Just can’t justify a fancy smartwire to hit the starter and turn on a single water pump. 😉

[@jettech1041]

Wiring still gives me migraines but you did a great job explaining what you do to wire a car! 👌 when you say run the grounds directly to the battery, can you show us what it looks like at that point. Thanks

[@StreetCarJoe]

Yeah I’ll go over it in one of the upcoming vids. But pretty much the ECU has a wire that goes directly to the negative post of the battery.

[@StreetCarJoe]

No problem! 😎

[@windward2818]

The large gauge starter feed (Red) and block ground (starter return Black), both look like size 1AWG, are needed for the starter currents while cranking. If you get the thick fire wall rubber grommets and protect with heat shrink and/or split rubber heater or fuel line you can go directly through the firewall without the added resistance of the pass through and the lugs. You can buy very thick red and black dual wall heat shrink which will prevent any chaffing through the fire wall if also supported with fully cushioned P-Clamps to keep the cable from moving to prevent chaffing. You need a little flexibility (slack) in these cables close to the engine, because the engine will move on its mounts, especially during launch. If you put a 3/8 inch stud type red and black power point close to the battery in the trunk (keep to a 12 inches or less) you can use this as your star power and ground using the same 1 AWG cable (you can move up to 1/0, but this is not needed) without any negative effects on EFI or CDI or COP ignition operation. This way you can use a crimp battery terminal lug and not the gang screw wire clamps, which I think are higher resistance than the 12 inch common feed when hydraulic crimp lugs are used with a common power point. It looks like the car does not have an alternator so this wiring in the context of the build did not have to be addressed.

[@lse90garage]

Curious if there’s any other main battery terminals you’d recommend, I see you’re using the standard parts store ones but we always run into issues with the tension plates fatiguing and causing loose connections. Excellent videos so far man, glad you finally made a channel.

[@StreetCarJoe]

Good point. I've seen people use a variety of different ones. The ones I use are GM ones. Wether or not the quality is better than the parts store ones, who knows. Dont over tighten and I haven't had any issues...

[@honda250rashton]

Hey joe are you using a bolt and nut or the revnuts for the clamps used to hold the ground and power under and inside car. Thank you love the channel

[@StreetCarJoe]

Most of the p clamps holding wiring and stuff on the bottom side of the car are using small self-tappers. If it’s not something I plan on taking on and off a lot I think those are good to go.

[@richardspann8005]

If you have the battery inside of the car, in the passenger seat area. What size wire would you recommend for neg and pos?

[@bpowda84]

Do you use any kind of fuse/circuit breaker on the positive lead going to the front of the car? Or did i miss that part?

[@stanley6662]

Can you explain how the cut off switch is wired exactly and how it works? What wires run to the cut off switch and what actually kills the power? If that makes sense. Thanks Joe!

[@TMGAutoglass]

I would like to know that same thing. I will be wiring up my fox body as soon as these videos are done. I will follow your lead lol.

[@directdiscountusa]

I always thought that some of those wires you have going straight to the battery.... are supposed to go to the switched side of the on/off switch in the rear in case of a roll over/fire..... no? I know they work better straight to the batt... but if there is an accident the safety crew needs to cut all the power. at least the way i always understood it. thanks for the vid.... always fun to watch. and motivation to get my junk rolling.

[@StreetCarJoe]

The power leads for the ecu go to the battery. The relay board and switch power (which trigger on the ecu) are on the switched side of the cutoff switch. So if they kill the power, it kills power to the relay board which will kill switched power to the ecu and all the relays...

[@directdiscountusa]

@@StreetCarJoe correct. but there are still live wires when the switch is off. I only ask because i am going to wire up my car soon and EFI cars are a little different that the older prostock stuff we used to run. Good info. Thanks again.

Did I miss it but what gauge wire did you use for alternator and other wiring from battery to distribution block and cut off switch? Thanks and super clean work man!

[@StreetCarJoe]

It’s 4ga... but keep in mind this car has a mechanical fuel pump so it doesn’t have a huge electrical draw

[@gtpro700]

@@StreetCarJoe thanks for the info! Awesome work again. Keep up the content we love it.

[@mr.know_it_all]

Is there a vid where I can see how you wired the on/off switch? and do you not run a switch controlled main on/off solenoid for the power of the car besides the push on/off? Like switched power for the main power and relay power? Or do you just have constant power controlled by the push on/off switch? I just am worried about an accident and no way to cut the main power cable and not having a breaker and relying on someone cutting my main power In The rear of the car. If that makes sense.

[@trapperdude223]

Can I supply my starter and alternator off the same 2ga wire?

[@kevin_nagle]

Like Joe said, definitely wire the ECU & smart coils directly to the battery. I chased an issue with a car that has a Haltech & IGN1A coils, it was breaking up badly when it got into boost, almost like it was hitting a rev limiter at 4500rpm. Ended up being the ECU & coils were wired positive & negative to a distribution post inside the car & not to the battery like Joe mentions. Wired them directly to the battery & problem solved! Keep up the good work Joe, looking forward to more wiring content 👍🏼

[@StreetCarJoe]

Thanks man! Yeah I've seen too many issues not grounding stuff properly lately it seems...

[@nfg_coyote4615]

Hey joe, going to put the battery in the trunk in my 2019 mustang. What gauge wire would you recommend? 2? Thanks man. Love the content

[@juanortega-flores9765]

How thick should a positive wire be coming from the power to the distribution block?

[@juanortega-flores9765]

What gauge wire are you running? You might need it be a bit thicker to compensate for all of that length! At least on my car, since it runs to the back as well, I use 2 AWG wire

[@nemesisracing1283]

When you run the grounds for your inputs and 5v switches are the grounds all tied into a terminal trip or all seperate?

[@StreetCarJoe]

Patience... That will be video 4 or 5. But no I won't use the terminal strips. I will be using the step down connectors to hook up all the power and grounds for the inputs/outputs.

What's up Joe - I ran 4 gauge power and ground cables per your instruction from the battery to bulkheads on the passenger side of my car. While testing the starter, it drags for a sec and this picks up spinning over. My car is a 64 Plymouth Fury (long car). Do you thing I need to try 2 gauge to assist the starter with power?

you can measure voltage drop on the power and ground circuit but personally, on a street car I run 1/0 or at bare minimum a 2ga

[@StreetCarJoe]

This car and my car don’t have enough electrical components to draw enough amps. The have mechanical fuel pumps. On a car that has a big electrical fuel pump and a 200+ amp alternator; I would be using 2ga welding cable. Never bigger

Always thought the alternator could go to the bulkhead power distribution? Better to go direct to battery?

@@StreetCarJoe oh ok, I’ve always used the waytec 2 post kill and just ran the bulkhead power with alternator/starter to the battery side of the kill and seems to work good!

[@Amxracer]

[@daddyoisback]

Simple question for you,but I've been wrapping my head around it and looking. So I have the terminator x, and fues/relay panel with a rocker switch panel. Question is, I start my car by poweing up the switch panel then I have a starter switch ,once the car is started and running how do I turn it off without powering off everything? Which is what I had to do with the old 0411 ecm . But now with the term I don't want to kill power to everything just to shut the car off. If this confusing I appogize, probably why I couldn't find an answer with Google and KZbin search

[@StreetCarJoe]

I don’t know how that switch panel is made or wired up. But when I wire up my switch panels, the ignition switch turns on the Holley and whatever other switches that I want to be tied to ignition. The other switches are powered by the battery side so they have power all the time and will stay on even if the ignition is off. Hope that makes sense 😎

[@daddyoisback]

it's just a basic amazon panel , but I changed out the start rocker to one that has 6 posts on it, I know I'm confusing as hell. but I have a good idea of what you are saying from your reply. by the way love your videos and attention to detail. I'm a budget guy and like to make my own stuff, but I buy what I have to when it is important. and thank you for the quick reply on an older video.

[@philbetthauser9547]

How do you determine what size power in ground to run from the battery up to the polecat? Is there such a thing as being too big?

[@StreetCarJoe]

Yeah you can do too big. There is a big formula for distance and amps drawn to determine power wire size. I’d say most cars with a mechanical fuel system are good for 4ga welding cable. If you have electric pumps and a bigger alternator like a 200amp, I’d go 2ga welding cable. Quality wire helps a ton as well so you don’t have to use huge wire.
