Ok here is my problem. I have a 88 std model hatch with the car's entire wiring harness except the engine bay wiring harness. And I have a 90 civic si engine bay wiring harness, that I'm trying to use but my buddies told me it won't work because the plugs are different. I also have a 88 crx si wiring harness laying around would that work? This is for a b16 by the way. Thanks for the help, I need it And I did do a search but nothing was found on this subject.

 

Ok, I found out its a pain in the butt to use the si wiring harness. So I guess I"m going to have to rip out my entire car harness out of my si . I was trying to advoid this route by trying the si harness but I guess it too much work. So I have a long night ahead of me.

 

You will spend less time modifying your std harness. Just a quick tip.

 

Its too late now I already have the entire car wired up with my stock si wiring harness. Pain in the *** to say the least.
