For my track car i took everything out that didn't make the car run or power my gauges. I am about to run through the harness on a second and third car that is keeping the stock ecu. Is there anything i can't remove out of the harness, anything that needs to stay (aside from the obvious)

I really don't want to loom it out like i did to my car and have the stock ecu need something stupid to run and have to rewire it back in. The check engine light scares me..

And, since everyone love pictures, here's the stock 94 harness as it currently sits:

 

where are the pictures? :P

 

I swear i put it in there, sorry about that

 

omg..that's enough! It's enough to give me headache!

 

Buy a second one to use as a map after you pull that one apart. Put a ziptie on all the plugs you don't need so you know which wires you need to pick out. It only takes a few hours to do once the harness is out. I use the air bag fuse in the kick panel as a 12v source for gauges and switches.
