Im wondering what harness and ecu i should use for my JDM B18C GSR swap and auto to manual conversion in my 99 ex. I need to know which one will be the easiest when it comes to wiring, and the one where i will have to add the least amount of wires or none at all, and if just using that harness and ecu it will run perfectly and be pretty much plug and play. Im debating on running a 99-00 si harness and ecu, or a 99-01 teg harness and ecu. Will both work and run perfectly? Could i use either an obd2 a or b (96-00) harness, with the obd2b ecu, or does it need to be obd2b to match up with the ecu? Is the pt2 the 99-00 si obd2b ecu?, just wondering because i know where i can get one, if that would work. And if anyone happens to have either of those 4 items laying around, let me know. Thanks.
