This may be a 2005. Mfg date 6/05 air manifold looks a little different. Stop lamp switch is in upper right position. Switch is working and it drives relay #12, coil is working, no power to common term 30, place power on term 85 (to simulate contact closure if power was present at 30), and brake lights still do not work.This pressure switch may drive another relay, but I do not know. Need that schematic.

no, it does not. I cannot seem to find the correct diagram for you. I will opt out and see if anyone else can secure it for you Roy
