So I’m at a lose hear. I’m not very good with electrical stuff at all but I have been at this tail light issue for couple days. I have a 1994 pickup and the tail light fuse blows as soon as I turn the running lights on and I’ve check all fuses I switched the tail light relay I unplugged the harness under the passenger seat to eliminate the rear of the truck still same thing I have all the pig tails unplugged from the harness that goes to the front marker lights I have the radio unplugged the dimmer switch unplugged the cigarette light unplugged still same thing fuse blows immediately Can anyone tell me where to go from here
