lol just did a z6 swap in my crx si you will need a jumper harnes for the dizzy obd0 to obd1. and yes the jumper harnes for the ecu also. the vtec wires are going to have to get wired into the ecu jumper harnes. find the pinout for the ecu and see which one is vtec. you can also make it eaiser to jump the ecu for the codes if a check engine light comes on.
