I was labeling all the wires on the PCM and found 1 that was not there. I just wondered if anyone knew if I needed it. It is pin 56 on the blue PCM. It says it is for fuel temp/composition signal. It is remotely possible that I removed it on accident last week when taking out the ones I don't need.
Thanks for any help.
