I've got a 95 LS-SE running a 98 gsr motor all on a P72 ecu. Now, the car didn't originally come with vtec, so i know that i have to run 4 wires to the ecu. but which ones?

knock sensor, vtec selonoid, vtec oil pressure sensor, and secondary o2 sensor. plus since its a gsr a secondary intake selonoid.

 

Rainforest, you seem to be pretty knowlegable about hondas, what all would I have to add if I am installing a d16y8 sohc vtec into a 91 crx? I have the complete wiring harness all the way to the ecu, obviously i don't want to use the obd2. Would it be easier to transplant sensors from non obd to the y8 and get a zdyne, or should i make a harness and use the y8 wiring? I am near the tarpon springs area if you would like to help me
