ill be doing a d16z6 swap into my rex ..i bought the motor from some guy and it came with tranny,clutch ,ecu ,shift linkage,axles but no wiring harness could i use my d16a6 harness on the z6?? and is there anything else that i might need to do the swap?it also should just bolt right in too?

 

you need to change the drivers side motor mount to your d16a6 mount... use your stock engine harness.. unless u are converting to obd-1... just put your stuff on that motor and u are good to go... also i need something like rpm switch or vafc to control vtec
