Quick question. I am swapping my D15B7 out of my civic DX for a slightly more powerful D16Z6. Do i need the engine wiring harness from the donor car or can i use the DX wiring harness? Other than that, am i correct in thinking that all i need for this swap is the motor, tranny, and the P28 ECU?

 

use the harness from your motor, and modify it if you need to. and you should also need the ecu for the motor that your putting in. good luck

 

Anybody have any pointers as to how to modify a non-vtec wiring harness from a 93 civic dx to a 92-95 civic si vtec wiring harness? Any web sties devoted to step by step instructions?

 

hope this helps. read it thouroghly. since your putting the whole motor in, you wont need half of that info. but your wiring is near the end of the page. i would read the whole thing anyway. good luck
