So after running an Air Lift Auto Pilot 1st gen for 10 years or so, I will be upgrading to their 3H system. I will have to modify the front section of my console to hold the new controller, & make a mounting plate for the manifold. Got some stainless plate yesterday in 19 & 20 ga, & made a mock up of what I will do @ the console. The Auto Pilot still works & have an extra sensor, & 8 3/8'' nickle plated ASCO valves with all brass fittings, slow downs, & Din connectors. May have an extra valve also, all will be for sale. The valves alone cost me $520. Make an offer .
Working on the front console now & than remove all the existing stuff & install the new,will go with the pressure senors first, test drive & than the height sensors . Ends up you only run on one or the other.
