Hi, I have been helping my friend swap a ZC motor into his 4door lx. the motor has physically been swapped in and everything is hooked up except for electrical. The place he bought the motor from included an integra wiring harness. He told me that we needed to use this harness instead of his original seeing as how the original was DPFI and the new motor is MPFI. We hooked up the new harness as much as possible. Then we read a swap tutorial and I changed all the wiring that I was told to on the ecu side (depinning plugs and moving them around). My question is did I need to do this since he is using the integra harness? I am just looking for some quick quidance. I thought the research on this had already been done by my friend but I guess not so now im trying to find out.

 

use your original engine harness and convert to mpfi...!!!

So what can I do if we already have the ZC in the engine bay and used the integra harness? Can we use the integra harness or is it still possible to switch back to the old harness? Which would be easier? Thanks for the help guys.

 

switch back to the stock engine harness and follow the dpfi to mpfi conversion link that i provided you...!!!

 

Ok. Thanks man.
