Thanks fastEddy. The gen1 tailight set up uses the same 2 bulbs for running light, brake, and turn. I spliced into the red/green and hoping to get brake and turn lights on the trailer operational. Nothing worked. This has to be easier since there are many gen1 monty's out there trailering stuff. Just looking for specific wire colors on the monty harness that i have to splice my 4 flat into to make things legal.

Thanks to all who input.

91 LWB 3.0 w/300K. Nothing fancy yet...still getting the quirks out and cosmetic fixes.
