Installing LMC's Universal blinker 34-4900, 7 wire setup. I studied the tech tip here, the wiring diagram supplied by LMC with the blinker mech, and a wiring diagram of how the truck was originally set up to help me figure out what goes where. Hooked it all up and got nothin'. I had my wife hit the switch and the brake with the truck on and got an interesting symptom.
With the hazards on AND the brake depressed the Flasher ticks and my front right blinker (or front passengers side) was lit up solid. No other light on or blinking other than the red indicator flashing on the switch itself. Thats the most I can get out of it so far.
At least I know it has power and the grounds are good. but beyond that I'm stumped.
I think I found the plug that is directly before the directional switch's original location (in pic 2) and that's what I hooked the wires for the lights up to.
Here's the diagram LMC provided (pic 1) the diagram of my trucks wiring originally (pic 2) and the way I wired the blinker up (pic 3)
EDIT: truck wires on left, signal switch wires on right.
Light Blue/Yellow - left front Dark Blue/Green - right front Pink/Orange - left rear Violet/Brown - right rear Orange/Red - stop light switch Black - flasher L position Blue - flasher P position Red - flasher X position
thank you all in advance.
