How much of this harness behind the dash do I need? I realize that's an extremely vague question but I'm sitting here looking at wiring diagrams and coming to terms with the fact that I'm wiring retarded.

I know I need the 3 plugs for the instrument cluster and the headlight motor/hazard unit for functionality but how much of this other **** can I ditch without hating my life?

all a race car really needs is fuel pump relay, fans, ECU, dash, lights

Probably the only thing that you can take out without hating life is the audio stuff and the airbags. Airconditioning and cruise control as well. I guess power windows and power mirrors if your car had them. Basically all the options that the car came with. I'm just guessing, I've never actually done this though. IMO a hassle to save 3 pounds. Just lose 3 pounds yourself.
