Completing ECU and DASH to engine harness (GSR)

I am checking off what I need to complete my b series swap and I am stumped when it comes to what connects the engine harness(GSR) to the ECU(P72). As well as what connects the engine harness to everything under the dash (and whatever I’m missing)

note: b18c1 into a 97 EK CIVIC

Re: Completing ECU and DASH to engine harness (GSR)

You cannot use the GSR engine harness. You must modify a '96-98 EK engine harness to fit your GSR engine and then find a '96 GSR ECU, or purchase an adapter harness to convert from OBD-2A to OBD-1 if you have a '94-95 P72 ECU.
