my friend just got a 4th gen civic lx in with a zc swap in it at his shop the kid that did the swap can't get it to run and brought it to my friend. heres the problem it looks like the wiring is wrong and we need schematics we played with it for a couple of hours and it trys to run but no luck. the wiring harness at the ecu has been cut in a few spots and we can't tell if the harness for the zc was used or if the original ecu was modified to work. anyone got wiring diagrams or schematics anything would be a big help.

i have diagrams somewhere, ill try and locate them and e-mail them to you.

 

i tried those from the hybrid page, his wiring seems ok at the ecu but as soon as it exits the firewall it becomes a nightmare maze of wiring. ughhh!!!! those diagrams would be a big help thanks.

 

Welcome to wiring hell...

Try and label each wire that you can figure out. It might help some.

 

tell me about it (smallest violin playing in the background)
