Thinking i might be putting my 396ci lt1 and 4l60e trans in a notchback mustang and want to keep it f.i. Do i need the complete harness or just the engine trans harness and computer??? Is there 2 seperate harnesses?
any help would be great thanks Tim

 

If I am not mistaken you will need the interior one also to wire up all the gauges etc. All of these go to the pcm also but I may be wrong. Anyone wanna chime in that has done this?? Good luck man and let us know how it goes

 

I have all autometer gages so i don`t need the interior harness??

 

all you need is the engine harness(is both engine and trans harness) and PCM, you will need a harness from a A4 car, and you will need VATS programed out of the computer

 

Maybe you should go ask them Ford boys. Well wait nvm you are doing them a favor by putting a Chevy motor in the junk mustang. The ONLY thing good that ever came out of Ford's production line was the 9"...

 

oh, and use the output from the PCM for your tach signal

its pretty easy to do, I have a LT1 from a 94Z in my 90 K5 Blazer, running a 700R though(manual trans harness, and T/B from a 93)

 

What K member are you using?

 

oh, and it will help to have the matcxhing connectors for the LT1 engine harness, then you don't have to cut the engine harness any
