trailer wiring
 

I have a 2002 dodge cummins ram 2500. I want to check to see if my trailer plug [7pin] Is wired right. Does any one know what wires go were? thanks for the help. Ted

9 o clock is left turn signal- 3 o clock is right turn signal- 11 o clock is running lights- middle is back up- 1 o clock is aux-battery wire. the trailer brake and ground are 5 o clock and 7 o clock. i forget which for sure is the brake but i think its 5 o clock and the ground is 7 o clock. hope this is some help. you can take a test light and check them out. this is the truck wiring

Get you a test light and check the outlet on the truck and then compare it to the trailer. That's the only way to make sure you are correct. I'm sure If you google search im sure you can find a dodge factory wire diagram.
