The EX 4dr engine harness won't help get your vtec up and goin, did you have plans for an obd1 swap or a shift light/throttle switch style vtec engagement?

Personally i've don't the dpfi to mpfi swap and added the wires from the ecu to the engine. Maybe some others can comment as to the interchange on the engine harness' from the DP injection to the MPFI.

 

you need to use your stock harness and convert it to mpfi. you can't just drop in an engine harness thats mpfi unless the car was mpfi to begin with. the extra wires for it are not present in a dpfi cabin harness.

for vtec to work how it was intended you need to convert to obd1 and run a p28 or some other chipped ecu with a p28 basemap. once you do the conversion you'll be able to use this.
