: That sounds right to me, it's been a long time since I worked at the RV/Cap
: place but I recall the 4,5,6 & 7 pin wire configurations like this.

: 4 Way Systems are typically wired

: Green = Right Turn & Brake
: Yellow = Left Turn & Brake
: Brown = Tail/Running Lights
: White = Common Ground

: 5 Way (same as 4 Way plus)
: Black or Red or Blue (on various flat 5 way I've seen all three colors used on
: the 5th pin) = auxiliary power wire (could be used for brakes, however brakes
: are typically wired blue though I have see black used)

: 6 Way Systems (same as 4 Way plus)
: Black - 12V Positive (center pin on round 6 pin connectors)
: Blue - Electric Brake

: 7 Way Systems
: Pin 1 (lower right pin on truck) = White = Common Ground
: Pin 2 (lower left pin on truck) = Blue = Electric Brake
: Pin 3 (upper right pin on truck)= Brown = Tail Lights
: Pin 4 (upper left pin on truck)= Black = 12V Positive
: Pin 5 (middle right pin on truck) = Yellow = Left Turn
: Pin 6 (middle left pin on truck)= Green = Right Turn
: Pin 7 (center pin on truck) = Orange = AUX (I believe Dodge typically wires
: this into the reverse circuit, both my trucks with tow packages came that way)

    To back that up, here's a good site which has diagrams of the vehicle
and trailer ends of both 6 and 7 way trailer plugs, which may be helpful
if you decide to go probing around with a multimeter or test light:
