If your 1998 Dodge Ram came with a 7-Way and you need a replacement you can use Pollak 7- and 4-Pole Trailer Connector Socket, # HM40975, and Pigtail Wiring Harness, # PK11998 if needed.

The Hopkins Endurance Multi-Tow 7-, 5- and 4-Way Flat Trailer Connector, # HM48470, can be used as well but it is a hardwire connector meaning you would have to attach existing wires from the truck to the connector according to the wiring diagram I have linked for you.

If the truck came with a factory 4-Way, you would need to use Adapter 4 Pole to 7 Pole and 4 Pole, # 37185. The 4-Way on the truck would plug into this and the remaining wires would need to be hardwired. White is ground, purple connects to reverse light circuit if needed, black connects to positive battery terminal via a 40 amp circuit breaker, # PK54540.

The blue wire will connect to a wire that terminates at a connector under the driver side wheel well. To finalize installation the blue wire will need to be spliced into this point unless you do not plan on using a brake controller.

Since additional wiring will be needed to make these hardwire connections, I recommend using a 4 and 7 Way Installation Kit, # ETBC7. It comes with extra wiring, circuit breakers, and other parts needed for installation. I have included a link to an FAQ article explaining the installation of an ETBC7.
