My new to me 1980 C20 stepside w/TH350c was converted to a flat bed when the original owner purchased new. The flat bed frame does not have reverse lenses. It appears the PO wired in some spot lights on the cab protection frame that he manually engaged with a long throw switch. I’m trying to retain these spot lights but run them through the neutral safety/reverse switch attached to the steering column. I see that there is a blue and green wire. What I can’t determine is which position on the fuse box this blue wire connects to. Any schematic I can find on line is too low quality to allow me to even determine if this circuit is fused. Can anyone confirm that there is indeed a fuse for the reverse lights on this series truck? If so, do you know which position it resides? Thanks in advance for any help.

Welcome to the site.
Go here for electrical diagrams.
Go here for a complete set of manuals.
How much of the truck is original? Is it a manual or auto?
It's nice to see some our trucks used as work trucks. Every now and then, I see a C20 with a work box bed on it. It's really cleaned up. Two tone light blue and white. I'm not sure if it's used as a work truck or company show truck. One day, I'll follow it and ask the owner.
