i'm doing a d16z6 swap in 88 rex i have read alot of info on this site about this swap but i have a few? should i use jdm vtec ecu w wich is obd0 and convert this engine over to obdo?or should i get the ecu jumper and run a p28 and keep it obd1? does the jumper harness have the 4wire o2 hookup and the obd1 dizzy hookup also the fuel injector plugs are different.does this jumper harness fix this or is there another one that does the engine bay .i saw there were extra wires coming off of it is that where the go also does this include vtec wires?
