mjunda - thanks for the info - looks like you are right on the money.

Just checked and the connector (located where Fastdrmr indicated) is a 6-pin connector. Furthermore, Courtesey Parts has changed their web site and they no longer show the $13 4 pin square to 4 pin flat connector as what to get for the 05, they show the $55 set up that mjunda talks about. (the info on courtesy parts is what lead me to believe it was a 4-pin connector in the first place.)

Pretty cool for those of you using trailer brakes. However, all I want are the lights (standard flat 4-pin). Looks like I gotta get the $55 and the adaptor, or do some wacky custom thingy. Kinda overkill to just run lights!
