B16A OBD2 into 97 EK

[1carbon1]

Please Help!!! I've got a 99-00 SI B16A OBD 2 going into a 97 Civ EK...

Could somebody help me with which wiring harness I should be using?

Could I use my 97 EK harness with the P2T ECU (99-00 SI)?

Or do I have to get the 99-00 SI harness? I've also got a spare P2P ECU from a 96-00 Civ EX...could i use that instead of the P2T ECU if i use my 97 EK harness?

you can run your harness just need to add some wires, if you use the engine bay Si harness plug and play.

how about the issue with the plugs that go into the P2P SI ECU being OBD 2b.
my stock dx harness is OBD 2a.
