I have a 2000 Ram 1500 with a problem, when I went outside this evening my trucks back up beeper (the kind that replaces the reverse light bulb) was going off and the backup lights were on.The truck was sitting for about 15 min since I got home and was in park with no keys in it. I unhooked the battery so it wouldn't drain. I think what happened has to do with the backup lights I added under the bumper wired into the trailer light harness. I did a search and alot of people recomend putting a relay in the wiring, I didn't. Did I burn up a switch somewhere?Any suggestions? (what to check, where the reverse light switch is etc.) Thanks in advance! Alfman.
