Question:

I would like to install the brake indicator light in the coach instead of on the rear-view mirror. all the connection on the coaches 7 place plug are full so I will have to run a separate wire from the toad to the coach. Do you have a wire and plugs for this?

There are a few different ways to get the indicator light from the Demco SBS Stay-IN-Play DUO Supplemental Braking System # SM99251 operating in your motorhome.

If you don't plan on using the brake controller circuit on your motorhome then you can connect the indicator to your motorhome by using that circuit. Tap in a wire from the stop light circuit on your towed vehicle to the connector at the front of your towed, making sure it corresponds to the brake controller pin on your motorhome 7-Way. Then you just have to connect the indicator light to the Blue brake controller wire as you can see in the linked video.

The second way would be to use spade-style connectors, Male # DW01896-1 and Female #DW01899-1, for a quick connect/disconnect between your towed and motorhome and you'll just route your own 14 Gauge Wire # DW02412-1 from the stop light circuit on your towed up to the location of the indicator light on your motorhome.

The third option is the easiest but also the most expensive and that is to use the Demco SBS Wireless Coachlink for Supplemental Braking Systems # SM99945. This sends a wireless signal from the Stay-IN-Play up to the monitor that you'll have mounted in your motorhome so there is less wire-running going on plus you don't have to add "connecting indicator light wiring" to your pre-trip checklist.

I've attached a review video of the wireless kit for you to check out as well.
