2014 T660 No parking lamps, no headlights and no left turn signals - Rocketman - 03-09-2025
Greetings All.
Got stranded last night when all the front lights went off . I currently check the node fuses near the steering which are good. I have a 2014 KW T660 vin# 1XKAD49XXEJ385248. I know that it is against the forum policy to publicly furnish such information as wiring diagrams. If someone has this wiring information can you please PM me.
Thanks Much.

Its most likely the wiring harness between the fuse block under the hood and the chassis node (under the front drivers side of the cab) is corroded somewhere along its route. It is a really common issue for them.
that was a terrible design, and it is common for those kinds of issues.
start pulling the harness apart and look for corrosion, etc... and corroded fuses/sockets, etc. in the fuse box on the drivers side under the hood, and where the connectors go into the node, etc.

Thanks Rawze, Got the right low beam to work but nothing else. I agree it’s a wiring issue. Will check those tomorrow.

find mux3 module under the truck , its a 3 connector module and it powered with 4 wires , probably one of power wires is not giving power to module and than it gives multiple light issiues
