Isn't there some kind of little module used on trailer brake hookups for jeeps? Like an isolator or something?

The factory tow package uses an additional 3 relays (stop,left turn,right turn), circuit breaker, and wiring that isolate the trailer lamps from the main circuits. Bundled behind a rear side panel.

Without the factory package, aftermarket kits including "converters" (3 relays in a box) and wiring perform the same functions.

Either way the additional relays/wiring keep the trailer lamps load isolated so it doesn't mess with the LOM, stock relays, etc.

You have to remove the vic and open it up and with a magnifying glass look at each solder point for any cracking or solder separation and if you find any re solder those.

question on the factory tow package wiring

i have the factory tow package wiring in my 95 zj and the only thing that works in my trailer plug is the parking lights. i took apart the passenger side of the inside quarter panel in the cargo area and started testing the wires with a test light. all the relays work minus the one that the circuit breaker goes to, could the circuit breaker be my problem? if so where do i find one of these, my local auto parts stores don't carry 10 amps just 20 and higher.
