No tail lights?

[blk jew]

Hey i have a 94 k1500 none of the rear lights work, blinkers are very dim. I've checked bulbs all look good and new bulb didn't help, couldn't find any bad fuses but maybe i missed one? Any ideas what could cause this? Thanks for any help in advance

Ok just pulled tail light and have power at all 4 pins of the plug coming from harness, so i'm guessing there's no ground there's power jumping to the ground wire?

Its backfeeding due to no ground. Check the ground at the rear bumper.
