Question:
I have a camper with electric brakes. I have a 1989 Silverado with flat 4 plug. Can a 4 flat to 7 pin adapter work to use to make electric brakes work. I have a brake controller installed are will I have to wire a 7 pin line and 7 pin plug to make the electric brake work on camper

Danny, yes, a 4 pole to 7 way adapter like the Adapter 4 Pole to 7 Pole Vehicle End Trailer Connector # 30717 will work fine with electric brakes since the blue brake output wire would get hooked up.

Hey Danny, how did things go with the 4-pole to 7-way adapter on your Silverado and camper setup? Did the electric brakes work smoothly once you connected the blue brake wire? Your update could make it easier for the next person wiring a similar setup.
