I am sorry to hear you are having a problem with the Curt T-Connector Vehicle Wiring Harness # C56331 on your 2014 Dodge Grand Caravan.

Since you are not getting power, I recommend first checking that the black wire that was run to the positive terminal over your vehicle's battery is securely connected to the battery terminal, and the fuse is fully inserted. Next check that this wire did not get pinched or burnt causing the power loss. If the wire was damaged in any areas, you will need to replace the damaged section with # 12-1-1 and heat shrink butt connectors # DW05745-5.

If the power wire looks good then using a circuit tester # PTW2993 test the black, green, yellow, and brown wires going into the module while you have the turn signals and head lights on. If you are getting power on these wires but not on the 4-way connector, then there is a short inside of the module, and the harness will need to be replaced.

I included a video of the #C56331 being installed for you to take a look at.
