Amp Power Steps

Yesterday, I installed the Amp Power Steps 79106-01A Override Switch, which gives you the ability to "lockout" the automatic functioning of the steps, and either keep them fully deployed or fully stowed with the touch of a button. This kit only works with the later model controllers that have both a 9 pin and 8 pin connector.

First, for the switch, the installation requires drilling a 3/4" hole in the dash, and I just couldn't bring myself to do that, because I don't like drilling holes in the dash, and secondly, there really isn't that "perfect place" to install the switch. After looking for quite some time, I decided to install the switch in the driver's outboard seat track cover. 

It's convenient, yet out of the way. For drilling the hole, I used a 3/4" aircraft sheet metalworking counterbore with a #10 pilot. (Pictured.) I also routed and brought the 3 wires from the 8 pin connector on the controller into the cab by way of the emergency brake cable grommet under the carpet in front the driver's seat, (I already have other wires going in there,) so it was very convenient to where I installed the switch. AMP provides more than enough wire.

One thing worthy of mention is that the AMP wiring instructions included in the kit are misleading. The instructions don't say whether the "view" is from the front of the 8 pin connector, or the rear of the connector. I had to call AMP Tech Support for clarification, and the view is from the rear of the connector. My "cheat sheet" is included in a photo. 

AMP has no date for updating the instructions. The connector also has three "dummy plastic plugs" where the three new wires have to be inserted. These plugs are best removed with a wire pin extraction tool, (pictured,) as the plugs are barbed, and almost impossible to grip and remove with just a needle nose pliers.

Other than that, it works as advertised, and worth the $35.

The reason I decided on the switch is because if you use the "standard" method for keeping the steps deployed, (open door, put foot on step, close door, wait 2 seconds; Step stays deployed until next cycle,) the step stays deployed just a little shy of flat, and that bothered me.
