I just purchased and installed SMI (SilentPartner) based on this thread. The hardest part was pulling the hose and wires through the firewall of our turbo PT. I found the main wiring harness and pulled everything through the grommet. Connecting the vacuum tee was made hard only by tight quarters. I called my coach maker and car dealer and both gave me the correct wire to tap for the brake light signal. The brake cylinder did take some time to adjust so that we still had full pedal travel. Took a few spins around the block testing the brakes in a panic stop to be sure the brake cylinder wasn't interfering. The SMI was complete except that I had to add some additional wire in the coach to install the transmitter and reciever at the drivers window, and I built a bracket for the break away switch instead of mounting it to the bumper. That kept Patty happy.

Our first 1600 mile trip was last week and it all worked great.I like the latched mode when we were in heavy traffic.
Thank you ALL

for your posts and helping me make a good decision.
Oh, it has to sit on the floor behind the front seat. I think I'll put velcro on the bottom of the box to keep it from moving around.
