Quick update for those interested. Took a few days breather to run some errands.
I re-seated the ignition switch plug, but no change. Still no voltage at J4 pin8.
Talked to Freightliner and Thor. Didn't get much new info. Got a vehicle interface schematic from Freightliner, which makes no sense to me. The fuse control boards are on backorder from Thor, 4 weeks out.
I think I can get a multi meter probe angled in behind the ignition switch to check voltage heading to the accessory relay. I'm at least hoping the red wire is from the battery.
If I get brave I'll try the jumper if all else fails.
