I just had to replace the Manual Temp Control (MTC/3 knob job) on the wife's RT Magnum (no heat). It's the same unit as in the WK platform. Come to find out that they do NOT support the early build 2005 MTC units any longer. Instead, they sell you a schmancy '06+ unit with an adapter harness.
The difference is the fan speed connector. The '05 has a small, black square connector with small silver pins. The '06+ has a large, rectangle connector with large copper pins.
This harness and newer control is a pretty nice setup and is 100% plug and play.
Part number for the harness is: 5174076AA. List price is $61.81. I talked them down to $48. The climate control can be had on RockAuto for a good price. You will have to search under 2006, obviously...
BTW, the climate control we got has the chrome rings around the edge of the knobs! Pretty slick. Slightly different art on the middle dial, and different elevations on the buttons and the upper "brow". It looks nice and functions well
Just thought this might help someone out with an '05 who has to replace this unit.
