Air to tow vehicle

I am looking for someone that can help tell me where I can pick up air to supply me tow vehicle auxilary brakes. I have a 2006 Alpine and I'm not sure where to pick up the air. I have no problem running the air line if I can get this info.
Thanks

Are you trying to connect an aux braking system in your toad?
Your post seems to ask for a high pressure air source.

The complete system should include a isolation device which would keep your coach brakes working even if the airline to your toad was ruptured.

Can you give more info?

Have you verified that you have air brakes on the Alpine-- most Alpines have hydraulic brakes.

You must install a proportioning valve in a hydraulic brake line to the rear axle. You can tap into the air system from the air line that goes to the passenger side so you drain the air system or from an empty port on the air suspension manifold and run that line to the proportioning valve. You can then run the air line to the rear of the coach from the proportioning valve.

The easiest place for me was to tee off the air line was on the drain bleeder line in the utility compartment ahead right rear wheel. It has 120 psi air pressure.


I installed the proportioning valve on the cross member ahead of the of the rear end.
