need help with flatbed wiring on 03

[run2trouble]

I have put a flat bed on my 03 and think I have some wires backwards. First of all when I start up the truck, I get a " lamp out" on the dash. When the clearance lights are off and I step on the brake I get both brake and clearance lights. Aside from that, my left side works perfect. But on the right side, when I turn on the blinker without the brake pressed it works fine. When I step on the brake pedal and have the blinker on it doesnot flash, I get the real fast flash on the front of the truck, but nothing on the bed.



A question I had was on the lights. There are three wires, red, black, white. I know the white is ground. The red is turn/ brake, and the black is clearance. Do I have to ground to the truck light plug, or can I ground to a bolt? For the brake and turn do i wire the red wire on the light to both the turn and brake on the truck?



Thanks in advance,



Ky

There is a TSB for the lamp out indicator. Check the link.

Good luck.

Also, it sounds like you could have one of the bulbs that went south. If the filament breaks just right it can cause all sorts of "goofy" problems - shorts the filaments so both come on, wont work 'cept when the turn sig is on, etc. Bad grounds will cause both filaments to work as it tries to pull the ground thru a different path.



These are just some of the problems found over the years. Check grounds first then bulbs then ???



SOTSU!!
