If you are trying to replace the 4-Way connector on the rear of your 1998 Dodge Caravan you will need to wire a new 4-Way connector, item # 18004, by function using a circuit tester, item # PTW2993. Attaching a new trailer connector properly should solve your trailer lighting issues, as long as the converter has not been shorted out due to the wires being exposed from the original connector breaking off.

If the taillight circuit is not working, you will need to follow the wiring back into the vehicle until you find the converter, the black box that the trailer wiring is coming out of. Test the brown wire on the trailer side of the converter. If the wire is working... view full answer...

If that power feed checks out okay, you'd want to replace the existing converter with part # C56331. On the trailer, trace each of the lighting circuits from the trailer connector back to the lamps. Look for loose connections, broken or pinched... view full answer...
