Hello ...

I have a 99 Honda civic 0bd2b race ready aka track. We want the cabin harness removed “ dash harness “ and make a new harness for the switches and etc. where I’m stuck at is what needs to be powered when key is on. I got eld , injectors , icm , obviously fuel pump . Im putting fuel pump and ecu on own relays. Because the main relay for fuel and ecu is two relays in one really. Im sure someone on here has made a harness for drag car or race car. I just want a basic harness without the bs that factory crap has on it. People say it’s not hard and don’t seem it, its just Honda has things powered up when key is on and I wanna make sure I add them to the fuse panel that I’m making.

I dont need anything like headlights , ac , heat , ETC. If there is any info laying around please share it with me. Been doing research everyday on this crap and really hardly anyone can help me out. I do have the ECU obd2b pinouts just need to know what to power up when the toggled is on or key is switched to on. like i said i know honda feeds power to some engine sensors .

Thank you so much
Not here to start fights im here to figure this **** box out haha.
