If you see a Yellow/Red wire in the same area, then that SR came from a S14 Kouki that was equipped with the triple DIN gauge pod. Y/R is for the oil pressure gauge.

Thank you for the extra input. I'm going to double check on everything you mentioned. That also gives me good reason to look further into the Y/L wire connection.
Took it out for another brief drive the other day and experienced less idle drop. Cold starts have been the best idles so far. Starts up and slowly steps down from about 1200-1500 rpm. I only experience idle issues after warm up. I have a backup P2M alternator to test out also, since the current one is old and beat.
I'm due to change oil as well since the new cams have had time to break in. Will see how the next few test runs go and come back with an update. Strangest part is just how inconsistent this has been, but further testing has confirmed idle will always drop below normal range when I turn on the AC.
I love Zilvia, you guys are awesome and thank you for helping me troubleshoot this thing.
