I would peel back any covering on the wires until you can make out the colors of the wires. Then start probing the wires with a test light while someone works the various functions in the cab. You should be able to figure it out.

Stanley, ive had the same issue with my 88 k1500. it was a yard truck, the guy torched the bed bolts and lit wires on fire, replaced all wires one at a time but my reverse lights come on at same time as my brake lights, and only one reverse light comes on when its "in" reverse. blinkers only work half the time, sometimes i have no brake lights at all. but i did exactly that, peeled back till i could see color, then ran wire. ONE WIRE AT A TIME. so i wouldnt mix anything up, i will admit im not a wiring genius. according to that process, the test light says they're hooked up right. ugh.....

Blinkers stop working when brake pedal is depressed brake lights to. flasher relay starts clicking super fast. why?

You may have a bad ground wire or a wire with corrosion or rust on the connection (s). Try running a wire from a good ground to the black lead on your tail light harness. Test functions on the different sockets. If this cures the problem, inspect all connection in the ground circuit for corrosion ( green or white buildup ) or rust. When you find the problem, clean the contacts with a pocketknife or wire brush until shiny, then apply a small dab of dielectric grease to the mating surfaces. The grease will ****** the return of the corrosion or rust. Failing that, run a new ground wire to the affected lights and cut the old ground so it cannot cause interference.
Hope this helps!!

The neddle is attached to the column via a thin metal wire and spring which then clips to the edge. Remove the trim above the column and look for the clip attached to the wire and a warn spot on the column and reattach it. :)
