RH Spotlight wiring
Posted: Thu Nov 25, 2021 4:06 pm
Howdy, this is a general spotlight wiring question, which I almost put in the general section, but I think it belongs here. I may have missed it, if posted before. In the nutshell, my 2014 Caprice PPV came with no spotlights. Rather, the LH spot had been previously removed. I wanted to restore the left side spot, and figured I would add one to the right side as well. I purchased both lights and mounting hardware. Took a couple days to get them installed (weather permitting).
When I put in the left side I found the original power lead for it, so yay for the left side. Now there was never a right spot on this car, but of course it was an option. There is no power lead for this in the right A pillar. The right spot power would originate from the passenger side front fuse box (#5 to be exact). I could be wrong, but I don’t think GM made a bunch of main wiring harnesses……each having different wiring combinations based on options. Hoping this is true, there would be a power lead for the right spot in the main harness that enters the passenger cabin somewhere…..then teminates at a point where, if there had been a right spot installed, the wire would have continued up the right A pillar to the spot light.
SO………does anyone know if this is true, and if so, where the right spot power lead would pass through the firewall and where it teminates ? I must say that the service manuals are not helpful in this quest.
Or, do I need to uproot the main fuse box to run an independent wire from it, and route it to the right pillar ? I guess I could make a jump wire from the left pillar spot to the right side and share the circuit as well. Ideas ? Thanks, Bill
