Larry,
My 2000 Marquis came from the factory with a brake air line already routed to the rear of the coach at the hitch (receiver) area, so on it I only had to remove a plug and install an air line quick coupler. However on my first Beaver, a 1993 Patriot, I had to run the air line myself. I installed a tee in the brake air line (not the parking brake air line) at the rear wheel air chamber, and ran a line to the rear hitch.
Your coach will probably be like my 1993, in that you will have to tee the air line at the rear wheel air chamber. On the SMC era Monterey (1997 to 2002) that have hydraulic brakes, installing the M&G brake system is more complicated and expensive.
I have been using the same M&G brake system (on two different coaches and two different toads) for ten years now and it has preformed flawlessly. The best source for installation information is the M&G factory. They have installed the system on all makes of coaches and toads, and they are very helpful to do-it-yourself installers. Call them if you have any questions.
