hey im about to do a b16 swap on my 1996 ek hatch and plan on using my d16y7 harness with an obd 1 conversion and run an obd1 ecu, cuz i dont feel like spending money on an ex one. just wanted to know if it would throw a check engine light. The guy doing my wiring has done many swaps and said it would be easy, im just worried about getting a check engine light. Let me know if its possible without throwing a CEL thanks
