For obd1 ecu and motor the pink wire goes to A17 ( you may have to run that custom from under the hood) and the other wire black/yellow (color?) goes to a switched 12v source. It may be different because your running an obd11 motor with an obd1 ecu, that may fawk everything, at least i know it does for a 99 b16 and a 94 (dohc) Sol Si ecu
