97 S14, 5 speed swap using Auto ECU and auto lower wiring harness

I have heard that if your engine has a CEL, even if you get the actual light on the dash to go away, the ECU still prevents itself from running a self-test, and thus you will not pass emmisions when you get your car inspected.

I have heard that you can wire your CEL into your airbag wiring or put a resistor in the CEL circuit to keep it from lighting up. I just want my car to pass inspection after the 5 speed swap.

So should I: A)Find a way to rewire my transmission so the CEL goes offB)Wire the CEL to go off and hope the ECU can still do a self testC)Use a 5 speed ECU and wiring harness (I already have a spare 5 speed harness - just need the ECU)D)Take it to a mechanic and play stupid

Thanks for the help guys!

i would read over the auto--->5spd write up on here (i think its in articles) and make sure all your wiring is done right.

and yes, if your CEL light is on, they will fail you on emissions
