How to Wire Electric Trailer Brakes When Adding 7-Way Connector to Trailer  

The etrailer brand axle #e32GR is pre-greased using a lithium complex multi-purpose grease like the #DX64TR.

Even though I cannot comment specifically on the grease you used because I am not familiar with it, I can tell you the best grease for trailer bearings is a a grease with a rating of GC-LB, which just means it is made to withstand very high…

We definitely have what you need to add electric brakes to your trailer. I spoke with Dexter to make sure I recommended the correct parts for you, and the spindles that were used on your 2,500 pound axle is actually the same one used on the very…

The Dexter D35 axle is a 3,500 lb trailer axle so for a bearing kit you would want the part #BK2-100 that you referenced.

No, if the breakaway battery on the trailer is dead and the pin is pulled out of the switch then no power would be sent to the trailer brakes and they would not lock up. If they do lock up then the brakes must be getting power from another source or…

Electric brakes have 2 wires located at the back. One is for power and the other is for ground (it doesn't matter which is used for which function). The ground wires should be connected to the trailer frame. The only other place that would carry…

You have a good plan! You are correct that once you have a functional 7-way connector and the Tekonsha Prodigy P3 #90195 installed in your truck that you will not need any other wiring on the truck. Going with a junction box like the #38656 to…

Red lithium grease such as #L11390 is one we use often here for installations and it is compatible with other Lithium formulas. I have included a link to our help article that covers grease compatibility. There are greases that are not compatible…

If you are referring to two white wires from the brake magnet that are coming from the rear of each electric brake assembly, then it would not matter which wire is connected to ground and which wire is used for the brake feed. The magnet that…

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…
