The issue is I still have a constantly on KSB and for the life of me, I cannot figure out where it's getting power from. I guess I'll trace the wire running to it back through the harness...? It should be getting power from the remaining sensor, no? Also, which sensor (if any) tells the grid heater when to come on at startup (PCM?)? For that matter, what tells the grid heater to turn off, the PCM?
