Tail light help

Ok, just got my new tail light harness for my 68 step side { old one was hacked } Now I have strong flashers no parking or brake lights, when I pull parking lights with flashers, flashers go dim, when I turn signal, opposite lights and is dim. All in front is ok. I am new to site and don’t really know how to navigate to find already asked questions. Any thoughts would help. Thanx

Re: Tail light help

check the grounds...........they may look grounded but check them anyway. Most people think the positive is the most important source but its the ground. Electrical failure often happens due to bad grounds. If they are all good unplug the harness at the back and check each wire with a test light (a helper comes in handy to change the signals and hit the brakes ect). Good Luck

Re: Tail light help

I used to have all sorts of electrical gremlins on my truck. A few years ago, I decided to ground everything properly. After 40+ years of rust and road grime metallic continuity to battery ground is diminished.

I grounded all the major components to frame - cab, bed, radiator support.
Then I insured a good ground from cab to engine (factory ground on mine was behind engine head on drivers side).
