Question:
I have a 2005 Dodge Ram 1500 w/ a flat 4 pin connector under rear bumper. I am installing a Hopkins 4 to 7 RV adapter part # 37185. Am I correct in that I need to run the blue wire to the brake controller and the black wire to the battery through a 40 amp fuse? Then plug in my TEKONSHA P3 BRAKE CONTROL with the correct harness for my truck? Thanks.

You are correct that you will need to make additional wiring connections to your Hopkins 4-to-7-Pole Adapter # 37185 after plugging it in to your existing 4-pole harness.
In your truck to install your Prodigy P3 Brake Controller # 90195 you will use quick-connect adapter harness # 3020-P, which plugs in under your dash. You will need to use 10-gauge wire # 10-2-1 (sold by the foot) to extend the brake circuit and 12V power wires back to your new 7-way. You will use a 40-amp breaker # PK54540 for the 12V power circuit.
