And both bk95td an buddy suggested it was GP relay. I took advantage of good weather this AM and traced the thick orange wire back to the 7-flatpin trailer wiring socket, to the position of +12V. Why the solenoid was set to energize off the FSOS circuit, I don't know. I currently have it...

Refused to start last week, glowplug lamp (WTS) would not light, which...
Confirmed. 1995 L65 Suburban, DLC pin F jumps LP.
ALSO: Easy nearby source of +12VDC is in the elec. panel on footwell behind emergency brake pedal. Lower LH corner, there are 3 small jacks immediately above the marking "DRK GRN." The middle of the 3 supplies +12VDC.
