Question:
Hello I need the appropriate 7 pin / 4 pin setup for a 2021 ram pro master 1500.

Expert Reply:
To replace a 4-Way/7-Way connector on your 2021 Ram ProMaster 1500 you need the Hopkins Socket Kit # HM40975.
Otherwise, if you're needing to ADD 4-Way and 7-Way sockets then you need the following parts:
- Curt T-Connector Vehicle Wiring Harness # C58DR
- Universal Installation Kit # ETBC7
- No-Drill Mount Bracket, Long # 18136
- Extra 10 Gauge Wire # 10-1-1 (on an as-needed basis)
If you also need a brake controller then I really like the Redarc Tow-Pro Liberty Brake Controller w/ Universal Wiring Harness # RED52VR because it can be installed virtually anywhere and the control knob doesn't take up much space. This will splice in to the wiring you ran for the ETBC7.
