I have a 329 DS, my question is I am buying a trailer for my new side by side. The trailer has electric brakes. The my has a 7 pin plug installed. Does this mean my will control electric brakes? I only ask because my truck has a brake controller but nothing in mh like my pickup
Sounds like your RV is prewired for a brake controller but doesn’t have one installed. This is typical of many vehicles. You’ll likely need to purchase a brake controller and connect it to the trailer brake harness in the RV.
