Automatic
Completely stock.
I just wired up some auxillary lights. I essentially followed the diagram below, except that instead of running the switch to the fusebox, I tapped into the high beams, since I only wanted the aux lights on when the high beams are on. The lights are grounded directly to the battery, the relay is grounded to a screw on the fender, and the switch is grounded to a stud on the firewall.
The problem is that now the high beams, and aux lights can be turned on when the Jeep is off and the headlights are off. So, where have I gone wrong? Also, when I took out the relay to make sure it doesn't drain the battery, I notice that I can still use the "flash-to-pass." Is that normal? I've never tried it before with the Jeep and headlights off, so I wasn't sure if it's supposed to behave this way.
Now the fan. I'm not sure if it's something that I did while wiring the lights, or if it's a previous problem that I didn't notice since I don't normally idle for very long, but the electric fan isn't coming on and it is overheating.
I did some googling and looking through the Haynes manual but I'm not able to find where the fuse or relay is for the fan. I keep seeing mention about trying to run the A/C to see if the fan turns on. The A/C was removed by the previous owner, and the fan did run until recently.
Thanks!
