What our customers are saying:
This is a great company to deal with. Super fast service and great products.. Called the company on Jan 30 (1pm) and talked to Product Information about a Actvator III Brake Control.. My main interest was to get the Controller as soon as possible as I was planning a trip on Feb 4th... Was told by the Product Information Employee that She could get it to me in 2 days (UPS ground).. I recieved the Activator III at 9:45AM on the 1st of Feb (less than 48 hrs...). You can't be any better then that... Thanks to a Great Company for a great product when I needed it.

Trailer Brake Controller Installation - 2005 GMC Sierra

Alright today on this 2005 GMC Sierra, we are going to install part number 90885, the Prodigy P2 brake controller and part number 3015-P, the brake controller adapter. First step that we need to do is to remove this cover for access to the port that is behind here. So we will undo this nut and pop the cover off. We will take our cord and just plug it into place. Moving on, we will reinstall the cover and then put the nut back into place. Alright next we will go ahead and install our brake controller bracket and we are going to do that on a sheet metal at the bottom of the dash here.
Trailer Brake Controller Installation - 2005 GMC Sierra 1500

Today on this 2005 GMC Sierra 1500 we will be installing part number 90195-3015P. This is a Tekonsha P3 brake control module and wiring harness. First we are going to install our mounting bracket. The customer chose to place it under the dash. I like to use an extra clamp as a third hand to hold it in place. Next, using the hardware provided, I will pre-drill two holes, here and here, to set our mounting screws. A second option instead of pre-drilling and using the screws that come with the mounting kit it to use self-tapping screws that will run straight in to the metal underneath the dash. Now I am going to install the brake control module. As you can see, there are two screws mounted on either side. You just want to snug those down tight enough so the module is secure. I like to set it at an angle. It is easy for the driver to read and utilize when necessary. 1:02
Trailer Brake Controller Installation - 2008 GMC Sierra

Today we are going to be installing a brake controller on this 2008 GMC Sierra. The part number is 5520, along with the 7-way replacement socket for the GM products, part number PK11916. We are going to start in the rear, installing the 7-Pole replacement socket. We are back behind the bumper here and if you can see this unit here is actually the 7-pole factory socket that we are going to be plugging into. So we want to go ahead and disconnect this off of the knockout that goes into the bumper. We are back on the outside of the bumper here and this knockout here is actually going to be removed. This is where the 20047 is going to be put in place of. Now that the knockout is removed, we want to go ahead and put the replacement socket in there. It just slides in and you want to line up the notches and just rotate it and it locks right into place. I am going to take the socket that we removed from the backside of the knockout earlier and plug it into the back of the 7-way here.
