I thought I had an 'aha' moment yesterday and that my next post would be one of triumph. Sadly, it isn't
Before trying the hack, I tried spraying some electrical components cleaner onto the J/B and harness connectors in hope that maybe it would penetrate a little and find the corrosion that Rick had been referring to. (I had the battery disconnected of course while doing so). I also did this on the J/B to the front left of the driver's side door (where the turn signal plug is). Before replacing the panel for that J/B a blue harness connector caught my eye because it had 2 BLU/YELs coming from it (in the attached picture). I didn't have the schematics handy yesterday but thought it was too significant a coincidence because it was also one of the connectors that was wet before I fixed (hopefully) the Leaking when it rains
Finally, when I disconnected the harness, I did in fact see signs of corrosion on the individual connectors. I figured that just had to be it. I sprayed it real good with the cleaner (but did not phyiscally clean the connectors yet as I didn't have anything to fit into the little square holes to clean with).
I waited a couple of hours for the cleaner to completely dry, reconnected the harness, then the battery. Nothing
Either that wasn't it, or (I would hope) the connectors need to be physically cleaned with something. No flickering of the personal light bulbs or weak light, still dead as has been.
I didn't yet attempt any part of the hack (nor did I do the BLU/YEL confirmation test yet). When I opened the hood I didn't see any easily reachable grommet that I could feed a wire through. The ones that were easily reachable and visible were pretty tightly in place and I don't know if they come out on the inside of the firewall in a place I can reach.
Any thoughts on that connector or wiring if the hack is still the way to go?
DD, scheduling that trip out to Wendy's is starting to look very appealing
