Had the chance yesterday to try getting at the instrument panel J/B. It was easy to remove the panel below the dashboard, and the metal plate behind that. After that, there was a metal bracket that one of the J/B bolts secures to. That one wasn't as easy because I didn't have the proper socket extension, but I managed ok. My hope was that I'd be able to pull the J/B down below the dashboard, or flip it around to access the connectors on the back side. I tried, carefully, to do so but in the end there just wasn't enough slack in the wiring without disconnecting at least one of the harnesses. I didn't have the stomach to try that because until we buy another car in two months, any mistake I make could leave us completely stranded.
The best I was able to do in this attempt was to snap a couple of photos (attached). One is of the front (or back?) of the J/B with the lower panel removed. The other was the best shot I could get reaching around behind it with my cell phone. Sadly, there was no 'aha' moment. I don't have the schematic for the connectors, and so can't determine which is the one of interest. I tried to identifying it by correlating the grouping of wire colors to the wiring diagrams I do have, but wasn't able to draw any conclusion from that. Finally, even if I could identify the correct one I don't know how I'd access it without being able to flip the J/B around; doing it blindly with one hand doesn't sound like an option.
At this point as much as I don't prefer it I'm willing to implement the hack solution, but it's not clear to me where the best place is to splice in to a 12V source. Any advice for finding a lead that is always hot (as interior lights require), and is protected by one of the 15A fuses?
I attached a photo of the 5 wires running up the left windshield column with the panel removed- 2 BLU/YEL, 2 RED/YEL, 1 WHT. Is it a good assumption that the BLU/YELs are the 12V leads to the personal and dome lights?
