Apparently those trailers I was towing were drawing too many amps for a unpowered tail light converter.

Still don't know why it was messing up the lights on my jeep but it doesn't do it any more....oh well

Thanks guys
Going through this right now, glad you got yours up and working....

Retreat? Hell, we just got here......

Update on 93 ZJ no brake lights:
GREMLINS! No other explanation. Cops stopped me and said my brake lights were out. I had replaced the LOM module a couple weeks ago and everything worked fine. Now, I have tail and blink but still no brake. When the incoming plug is disconnected from the LOM, all circuits check out fine. As soon as it is plugged in, the signal from the brake switch (white w/brown stripe wire) disappears. When I bypass the LOM and plug it up directly, the results are the same. So I jumpered a spare bulb directly to the incoming wire, it would not light the bulb, but it will light up the tester bulb.
I am absolutely stumped by this one. Meanwhile, the truck has an impound order on it if back on the road w/o brake lights. Wire the brakes to a separate relay that could be activated by the incoming brake signal?

Ouch, that sucks... Hmm.. That would be an ok temp fix, though I doubt I'd run that more than very briefly.. That's a little out of my zone of work, I'll have to let someone else take lead
