Ok you got me.... I'm not doing a LS1 swap but I was told you guys are the sh@&. I wanna convert my 2.8L carb motor in my 84 S-10 to EFI. I have a complete harness, engine, computer, and all the sensors out of a 87 camero. Is there some one who makes a swap harness, or can someone help me put the 2 harnesses together?
