I will be using a p07 ecu for the vtec-e , and I have the engine harness for the vtec so are all the 92-95 ecu haeness's the same or will I have to add wiring? boomslang suggested I use a obd0 to obd1 harness with ap28 ecu and change to a 4 wire 02 sensor. seems that would defeat the purpose of the vtec-e any help would be great.
