I put this on the TPI board but have yet to be helped and i was hoping that someone here could help me out. this is hard to explain for me, but i hope you guys understand what i am trying to say. OK, here goes. There is 2 plug for the wiring harnesses that goe to the ECM. Is one of them for the engine harness and one for the rest of the car? I noticed that they both go into one harness just before the fire wall. My second question is, can i seperate the two and just take off the engine part easily? I am swapping from TBI to TPI and I am figuring that they can be seperated, but i dont want to start seperating and find out that i am wrong. So can i just take off the TBI engine wiring harness after i seperate it and just swap in the TPI engine wiring harness?
thanks alot guys and i hope you can understand this

 

You can either re-pin your TBI harness to match the TPI harness like my dad did, or you can remove the TBI harness entirely and put in the TPI harness.
