Here are some pictures of a couple of clients recent installs.

This was a simple 5 x 8 trailer install. No brakes tied to this one.

This install is Pipe Dreams Marine trailer that they installed themselves.

This install also included a GPS tracking unit. This looks intimidating, but actually isn't.
This install had extra wires with the second siren, and the GPS unit. It also used all 3 door pins.

Another great install. Thanks Jimmy!
