I will be happy to explain the installation of the breakaway switch. First, mount the break away switch at the front of the vehicle, on the drivers side. Choose an area you can easily reach, with a surface of sufficient strength to hold the switch firmly in place, so that the break away pin (Figure 1) will pull freely from the switch. Mount the switch in a horizontal position, with the break away pin facing toward the motorhome. Ensure that the break away pin can be pulled freely away from the towed vehicle, without any obstructions.

Next, the Inter Connect transmitter (ICX transmitter) will be attached later; however, since the break away wiring harness will be connected to it, choose a location for the ICX transmitter now. Look for a mounting point on the drivers side of the towed vehicle, on the lower portion of the dashboard, where the end of the transmitter with the antenna and socket will be visible and accessible. Choose an area away from pre-existing components or electronics, and where the transmitter will not
present an obstruction or hazard to the driver of the vehicle, or interfere with the operation of the vehicle. The mounting surface must be of sufficient strength to hold the transmitter firmly in place, so that an electrical
connector can be plugged into and out of the transmitter.

Once you have found a location for the ICX transmitter, look for a pre-existing hole in the firewall (or, if there is sufficient space, a pre-existing grommet with other wiring) close to where you will mount the ICX transmitter, to route the break away wiring harness through the firewall. If there is no pre-existing hole or grommet with sufficient space, drill a 1/2 inch hole through the firewall. Drill from the engine compartment or from the interior of the vehicle, whichever is more convenient. Before drilling, make certain you will not damage any components on the other side of the firewall.

Route the wiring harness from the break away switch to the firewall (or, from the firewall to the break away switch, whichever is more convenient), avoiding lines, hoses, moving parts or hot components such as exhaust systems. Where appropriate, use wire ties to secure the break away wiring harness. Connect the wiring harness to the break away switch.

Cut through the included grommet on one side, slide it over the wiring harness, and fit the grommet into the hole in the firewall. Feed the remaining length of the wiring harness through the grommet. Then, seal the grommet with a silicone sealant. You will connect the wiring harness to the ICX transmitter later.
