SOLD Tailgate Harness fits '78~86 with or w/o defrost.
To add a simple self-diagnostic capability, wire a 12V lamp across the latch safety switch terminals, and mount it in the tailgate shell above the lock cylinder in the inside sill (through a carpet retainer hole if present). If either control switch is activated, and the only thing preventing the glass from moving is the safety switch, the lamp will light and be visible to a person using either switch.
