SMI Aux Brake System

Just recently made a deal with a private seller on an 01 DutchStar DP. A SMI brake system is included in the deal and the owner said if I know how to disconnect the wiring, etc. from his F150, I could have that as well. I plan to use the system with my 03 Dakota.

I have medium mechanical skills and am unfamiliar with this type system. Is it fairly obvious or might I get in over my head ? An option is to leave the wiring and hook-ups on his truck, just take the box and call SMI for a kit to install on my Dakota.

Any thoughts or suggestions will be appreciated.

SMI makes several different brake systems so it would help if you stated which one. I would suspect your best bet would be to find out which one he has and contact SMI directly. When I was researching my SMI Air Force One system SMI sent me the installation instructions. If you can get the installation instructions you can just work backwards. Most of these units are expensive so even if you had to pay to have it removed it might be worth your while.

If it is the Air Force One, there is a tee in the vacuum line going to the master cylinder that will need to be removed and a connector put in to replace it. That line is cut and the tee is installed at the time of the AFO install. Then, I think you can just remove everything else without worry. Should be an air connector, electrical connector and break away switch on the front of the vehicle. The box under the hood and the air cylinder that pushes on the brake pedal arm. A wire attached to the vehicle brake switch. Some air hose and a little bit of wire should be all there is.

I would find out which brake system it was and as suggested before, contact SMI. I'm sure they will give you the info you need.

Thanks for the responses. The owners sent me the original brochure in a pdf file. The wiring and vacuum hoses, and kill switch look pretty straight forward. The model is a TMAA...believe it's an older version, but am told it works fine. The coach is equipped with the g-force controller.
The folks at SMI said their techs would be glad to help should I run into problems.
