2015 T660. Reverse lights

[Moose]

Excellent find!

I spent two days with wiring diagrams, an ohm meter and a load pro going through every chassis harness. Narrowed it down to a bad chassis node. What Paccar wanted to change it and program it was well beyond reasonable even for stealershit standards. Plus 2-3 days without my truck and the whole demandated thing... The only function I couldn't get back was the 12v+ going to the reverse switch on top the trans, so I went and got a new keyed B+ from elsewhere, fused it and ran it to the switch and haven't looked back.

I found this in my stash, Not 100% if it applied to your truck but it gives a good explanation of what they do.
