Problem - signal light relay constantly ticking. Stops when you apply brake.
Tha problem is signal light relay constantly ticking, but goes off when you apply the brake. Now twice tonight ALL guages went crazy, with both the tach and speedo fling all over the place, all warning lights on, and odometer fading in and out...but the truck did not stall out, continued to run fine???
It sounds like you are intermittently losing the ground on your dashboard. Check the ground, or have a good mechanic look at it
Also check , your grounds, from fire wall in to your , fuse box, an or your nutrial wire from batterie you have a few grounds off side fire walls an a few from back fire wall going into the vehicle dashh an on your braking toggle under your brake switch so when you mash brake peddle your hit a toggle switch it's also grounds in beneath your dash
