Tiffin Allegro Bus brake control

Im new here. Maybe this has been covered. I'm looking to add a brake controller to my Motorcoach. I have heard that potentially there's a plug under the dash somewheres or wires under the dash that can be tied into for the brake controller to function. The coach currently has the 7-pin large connector on rear of the coach and I'm looking to pull a trailer with brakes. 2013 allegro bus. 45lp.

There should be a connection under the dash, should be on the left side of steering column but tough to find in the rats nest. Some look for days

Call Tiffin. Ask for the service department. They'll help.

It will be a small bundle of three or four wires on the left side of the steering column probably tied up with the larger bundle. It should be marked with a tag.

I'm assuming you have a Powerglide chassis. In that chassis (built by Tiffin) the wires will be to the left side of the steering column, but may not be immediately visible. In my bus they were behind the kick panel to the left of your left foot when seated as the driver. My previous Freightliner chassis had a 6 point plug, but the Powerglide had small white tags on the wires. My wires also had printing on them identifying the correct ones. VERY tough to see, but a very bright light and looking through the correct lens on my tri-focals really helped (LOL)

Chuck you need to do the same thing that I was told to do when I first joined the iRV2 forums, go to your profile and update the information with your RV info, that way folks can help you with your problems.

I have a 2014 Allegro Bus 45LP and am needing to do the same thing. Wondering if Chuck got this done and how it went. His wiring and mine would probably be exactly the same.

I hurt my back (temporary) when getting ready to roll. Could not manually do installation. Purchased a curt echomobile trailer brake control 51180 in lieu of hard wire because I was leaving and needed break control. It works good and I really don't adjust it after setup.
Disadvantage is need app to manually control it, but I really don't touch it.

Electric trailer brake controller install

Just installed an electric trailer brake controller on my 2016 allegro bus 37AP today. Had read online that there are wires already in place to do the install. Ordered a brake controller with “adapter” for my coach. It had a connector installed on the coach end. Looked under dash to the left of the steering column in vain for the other end of the connector. Also read online about crimp on butt connectors on the correct wires which are labeled for brake controller. Could not find those either. Put in a call to Tiffin Service. Had to wait on hold for around 30 minutes to talk to a tech. 30 minutes we’ll worth the wait. Explained what I was trying to do. Tech asked for a last 6 digits of my vin and confirmed I have a power glide chassis. Tech explained the wires are located behind the panel under the switches console to the left of drivers foot area. Wires are not visible just looking under there but feeling above the end of that panel you can feel wires. Gently tugging on the wires I found some that felt loose on one end and pulling the free end over the panel exposed the correct wires. They all had crimp on butt or barrel connectors and all were labeled for the correct wire to connect to the brake controller. Easy install once the wires were located.
