I am wondering about using a GS-R ECU side wiring harness to add the VTEC wires for my GS-R swap. I have a 93' Civic CX and I want the wiring to be especially clean/stock looking. I cannot seem to find the proper tool to use to add wires into my existing ECU connector and I wonder if anyone knows about using a GS-R harness instead. Is this idea overly complex? Has anyone done this? Any help or ideas would be great.
