I'm stuck on if I can still use my '94 Ex wiring harness for my H23a1 swap.

The main problem is the fact my car came with VTEC and the H23a1 USDM motor don't come with VTEC....I understand theres a wire or two for my VTEC but what should i do with them for my H23a1 wiring?


O yeah can anyone list the OBD1 and OBD2 type motors and what years they came? many thanks
