Really the only way to tell if you have manual or self-adjusting brakes is to remove the hub and take a look inside. If you can see a cable running at an angle (see included photo), then you have self adjusting brakes like the Electric Trailer Brake Kit - Self-Adjusting # AKEBRK-35-SA.

If you do not have that cable, then you have manual adjusting brakes like the Electric Trailer Brake Kit # AKEBRK-35

Hey Scott, so the Jensen Mechless RV stereo part #JEN25RR can be used to replace the in-wall Connex you have now. There isn't a plug and play adapter available as nice as that would be so you would need to manually wire all of the connections.

Hey David, it really comes down to the height of your toilet to determine what would fit as a replacement since the different heights correspond with different bolt mounting hole dimensions. Like if you have a standard height you'd want the…
