Question:

My coach is actually built on a roadmaster chassis as it is a 40ft diesel pusher with a 330 cummins. Do you know if this chassis is pre wired?

For your 2005 Holiday Rambler Ambassador motorhome, I recommend you use the Tekonsha Prodigy P3 Brake Controller # 90195. This controller utilizes a LCD screen that gives you easy to read and understand diagnostics and comes with simple presets to make set-up easy. It is proportional, so it will allow you to apply the trailer brakes at the same time and with the same amount of pressure so your trailer doesn't end up pushing or pulling your RV. It doesn't have the codes of most brake controllers so it is a game changer when any issue is present.

Your RV is made on the Ford F-53 chassis, so you will have the plug in wiring adapter # 3035-P found under your dash.

It is very likely that a Roadmaster Chassis is not pre-wired. You would need to use the kit # 5506 along with the Extra Wire # 10-2-1 to wire your brake controller. I've linked an article to the ETBC7 Wiring which is very similar to assist.
