I have a ek 4 door that I'm swapping a first gen b16 into . I'm using my same y7 harness and wiring up vtec with a subharness from rywire . I understand that I have to swap over the alternator starter and injectors that's already done . What I'm having trouble with is what connectors are needed and aren't needed . Confused on where these connectors go in the the engine so that I'm using a different obd .
