To pick out bearings for a trailer hub you will need to remove one of the hubs so that you can remove the bearings and get the numbers off of them.

Or, you can measure the spindle where the bearings ride so that we can pick you out the correct bearings that would fit the spindle.

It sounds like you are speaking of the wires for the brake magnets. If this is correct, you will need to connect one of the wires to the brake controller output wire on your trailer connector and the other wire will need to be grounded to a clean…
