Hi, My name is***** will be glad to help. We can follow up as needed on here. Professionals are not employees of the site but users of the site and help on here as time allows depending on their daily schedule. Sorry to hear you're having these troubles with your truck. Thoroughly inspect the wiring harness and connector pins within that circuit as well as all of your fuses/breakers and relays. Look for any corrosion or damage that would cause a short or open circuit. I do not have the schematics but I was able to find that wire number and its description for what circuit it involves. That is for your satellite tracking unit as mentioned below.

427 — Satellite Tracking Unit Power Circuit Breaker (Constant-Power)
427A — Satellite Tracking Unit Power Circuit Breaker (Ignition-Controlled)
427B — Satellite Unit Stoplight Signal Stoplight Switch Output
427C 16 Satellite Message Indicator Light Signal Satellite Tracking Module
427D 16 Satellite Indicator Light Signal Disable Switch
427E 16 Panic Switch Signal Satellite Tracking Module
427F 16 Panic Switch Return Satellite Tracking Module

I hope you find this information helpful. Reply back with the results of these checks if any further help is needed. It is a pleasure to help anyway I can.
