I'm not getting any juice to my trailer receptacle's right turn/stop pin. I'm getting continuity from the trailer receptacle forward to the C217 connector behind the left front fender, and the fuse is good (getting juice there too), but I can't figure out which relay in the IPM controls the trailer right turn/stop lights. It's not marked on the IPM cover nor is it in the service manual. What am I missing?

Hoping it's just that relay and not something else.

 

Are you ready for this? The relay is inside the front control module aka the fuse box. What a brillant move on Chrylsers part. My truck has the same problem and the module is bad. I would like to see if I can wire in an external relay because replacing the module would cost around 400. And I personally would not buy a used one seeing how many have failed. I would have to look at my wiring diagram tonight to be able to tell you what wires need to control the relay.

 

I had to buy a new fuse box for mine. around 250 if I remeber correctly

 

Was afraid of something like that. Looking at the diagram, the "Trailer Tow Right Turn Relay Control" is in the FCM and the relay itself is in the IPM (fuse box). Is the relay integrated right on to the IPM circuit board, and thus hidden from view? I was hoping it was one of the replaceable relays in the IPM near the fuses. Sounds like that's not the case.

I still need to check continuity from C1 to C217 but I'm guessing it's the relay.
