BMW E46 Race Car Build: Electrical & Wiring

- I get the rat's nest of a wiring harness thinned out and reinstalled, along with a new power distribution system. The car cranks over with a juicy spark at the plugs! All it needs is fuel and it should run.
I also reflash the ECU to bypass the immbolizer (EWS) so the car will start, since I ripped out the immobilizer long ago. I figured it'd be easier than dealing with security issues down the road.
There's still the fuel system and shifter that need to be done before the car can drive. Then, I still need to figure out electrical systems for the wipers, lights, and some other small things before the wiring can be considered finished.
I have a background in electrical & computer engineering, as well as experience designing the electrical systems on an FSAE race car, so this sort of stuff doesn't make me sweat too much.
The next part will be the fuel system, which is the last thing before starting the car. Then the shifter (which you may have spotted in the video already- I usually am working on multiple things at once) can get installed. Slap some body panels on, get a steering wheel and seat, do the whole braking system... still a ways to go before it drives. - Auta a dopravní prostředky
You are a beast, that bundle of wires sure looks intimidating!
yo man you’re killing it ! awesome build , can’t wait to see it all finished
This is a great channel - you should have way more views 🙏
Would like to see More about wiring my g.
Keep up the good work my dude!
Holy shit dude, what do you do for a living? You are very intelligent, this is no easy task!
Thanks- I have experience working with computers/wiring. My degree was in computer engineering, and I spent a few years on my school's Formula SAE team, which was very similar stuff. Now I am in software, after a short time in electrical engineering.
Hey @rainvillecreative5410 I've just gone through this arduous task of thinning the chassis harness and have deleted the GM5 module as well as the ABS/DSC module.
Im currently stuck and have a question about the starter solenoid poles. Can you tell me which pole was supposed to goto ground? In your video it seemed like it was the black and yellow wire, which i assume is the signal start from the cluster and the other wire was from the EWS?
Thanks!
It's been a while, I'm afraid I can't remember. I don't have access to the car right now to check. I seem to recall the EWS module providing ground to allow the car to start though. And the other wire would be the relay trigger.
This is a valuable video to me. I would subscribe if I wasn't already.
For the Immobilizer delete which flasher and forum did you use? i’m currently stuck with my car with a no crank no start, and ive had many tell me its my immobilizer shutting down the system.
I think MS4X flasher? I don't remember the forum. There is a wire going to the relay on the starter that the immobilizer uses to allow the car to crank, I believe by grounding it out. This needs to be bypassed. Once this is done, the car will crank whether the immobilizer likes it or not. Then all the immobilizer will do is prevent spark. I go over this briefly at 5:45.
Can I take my car to you for wire thinning I just gutted my e46
So I wouldn't really recommend doing this, it's a huge pain. I also don't have space to take on anything else unfortunately. Just disconnect the audio harness, I think it comes out easily.
My brain 🧠 hurts
bit wierd the way you did it but.. but what ever good work pal
