Brake controller install question

[dale farley]

Tim,

I know you are not asking which system you should use or which one is the best, but if you get bogged down with the controller installation and you are looking for an easy self-installed system, there is always a Brake Buddy or one of the other Progressive Braking systems (InvisiBrake) that are easy to install. I use a Brake Buddy that I purchased "used" a few years ago for a a couple hundred dollars. Of course I pull a girly PT Cruiser that weights almost nothing, and I do realize that a Brake Buddy or a PT Cruiser are not very Prevost-ish. As I keep talking about this, "maybe I need to switch tow cars and braking systems"!

I have used what Gill suggested on other controls where a 24 volt signal needs to be 12.

The trailer lights. Some a/c compressors. Very simple to use a 24 volt relay but simply hook 12 volts to the spade for the + battery instead of 24.

I hooked up a Prodigy brake controller to tow my hauler. I used the connections outside next to the drivers seat (Prevost wiring, not converters). There are some open lines that run to the back of the bus so I did not have to run any wires back and forth. Look at the door panel diagram and it will tell you which ones are available. Normally, the ones with only 1 wire attached go to the control box above your engine. All wires in there are numbered.

I also used the brake and signal wires in the rear box to complete the 7 pin hookup for turn signals, brakes, and 12V feed. There should be a diagram with wire numbers that link the front and back.

I grabbed the 12V feed from the front panel. Just put a meter on some of the areas to find 12V. I think the 12V power strip is to the right side.

I had a 1995 Liberty but yours should be the same setup. It has been sold so I cannot give you the specific wire numbers I used.

I used a Ford plug from a Ford that had a towing package and ordered the Ford adapter for the Prodigy from the internet. I think it was e-Trailer site. I did that so I could use the Prodigy on my Ford van to haul the same hauler. Of course it could just be hard wired if you don't plan on using the Prodigy in another vehicle.

So Ron, are you without a Bus right now ?

Thanks everyone. The 24 volt relay was my second choice if there wasn't a better place to get the signal.i will use a relay.
This controller will be for electric trailer brakes. I found the spare wires running from the front to the back. Since they are small, I will parallel two of them. The bus was already set up for air operated supplemental brakes on a toad. ( M&G I think) I plan to rig up a Jeep for flat towing a little later. Am I right thinking that there are are no controllers or lights etc. needed with the M&G system, only the air line from the bus bumper to the unit at the toad master cylinder?
Thanks for the help!

Yes you are right about the M and G,they also have a break-a-away option that I like and is easy to install.

Ok, good deal on the M&G system.
Thanks everyone for the tips.
