If anyone can supply a wiring diagram I’d appreciate it!

I need one for the Tail Lights and trailer wiring currently.

 

Which wire goes to the dash lights after the dimmer switch?

 

PM'ed you with a link to downloadable factory service manuals (FSMs)... Geno's Garage has paper-copy FSMs. You can also get a single-vehicle subscription to factory repair data and wiring diagrams on AllDataDiy.com

 

Thank You!
