First of all, I serached this topic and found ltos of information but and still confused as all hell so hopefully I can get some help on it.

I have a 1990 Rs project car that was orignally a TBI 305 and I just bought it from a guy who threw an L98 in there with a carb setup. So right now Im just kinda wondering where to start off. I got some wiring diagrams on both of the systems and theres a lot of stuff thast wired different. During my search I found that ppl keep saying you dont need to rewire too much? Now is there a how to thread somewhere that I cant find or what? Any help or links would be awesome.

thanks in advance

 

I just finished seperating my harness today. Not to say it will ever work again but, I hope it will. I'm assuming your not running the ecm(computer). I have a helms manufactures manual for mine and that has made the difference. My harness was out of the car. I'll start reinstalling soon without all the computer stuff. I'm not much help but if you have specific questions I'll try to help if I can. I know others here have lots more experience than I.

 

Thanks, any one else?
