I bought another BCM and after I installed it my security light comes on and will not start. I went through the re-learn mode with no luck. When I tried to read the resistance through the ignition for the Passlock is shows open. It does not have the keyless feature. What size resister should I put between the yellow & orange/black wire to reset the BCM value for the Passlock? When I re-install the original BCM it starts fine but never get a security light.

My previous post I said PCM and I meant BCM
