bd: I found it - quite by accident, but................
First, let me make a few excuses - - when I bought this truck there were wires everywhere in the engine compartment. The wires just for the plow and lights were spaghetti-like. The pump for the bed was located there too, which only added to the wires. As I disconnected I labeled everything, but the labeling was not as secure as it will be next time. Anyway, I found an unaccounted for, unlabeled wire, and I did a continuity test through the purple wire on the clutch safety switch and viola!
On the picture of the FBC the wire is just below and just to the right of the top left wire. Which makes me wonder, how do you connect wires to the connector?
Honestly, I don't think I could have done it without you. Appreciate it!!
