If your trailer is currently equipped with electric-over-hydraulic drum brakes then a good portion of the conversion process to change it to an electric only brake setup will simply be removing existing components that are no longer needed.

You will need to replace the hydraulic brake assemblies with electric units such as the etrailer.com # AKEBRK-12 if your Dexter 12K axle currently has 12-1/4 inch x 5 inch drums and re-wire the trailer accordingly. I have attached a great article on adding electric brakes that goes into the wiring process with a lot more detail. The hydraulic lines and actuator can be removed and but can use your existing brake controller to power the new assemblies.

If you have electric-over-hydraulic disc brakes instead of drum brakes you will also need to replace the hub assemblies. If you can let me know what inner and outer bearing numbers are used on your current hubs I will be happy to make a specific recommendation for this.
