Hmm... Do I know you? I was involved with pro rally out there from the mid 90's until my recent move to FL. I used to work stages with Diane Duran and more recently I was service crew for Jamie (215) and Gary (288).
I'll look up the VSS pin tomorrow.
Without your VIN this is my best guess. The 2010+ wiring diagrams are now VIN specific, but most things are pretty close not using the VIN. It shows two vehicle speed sensor outputs from the ABS module, pins 41 and 42, DG/YL and DG/WT
41 B22 VEHICLE SPEED SIGNAL 1 22 DG YL
42 B222 VEHICLE SPEED SIGNAL 2 22 DG WT
Looks like he got you covered. I work at a Subaru shop but a couple of folks have Dodge logins because we've got Dodge/Chrysler/Jeep/Subaru and a used car lot all bunched together.
I don't think we've ever really spoken, was your old truck green with white door number backers (or something, it's a bit fuzzy).
I never made it to the Alcan, but I know a few people who run it. Small world...
