I'd rather it stay on all the time when the AC is on in the cab not just when the compressor is cycling.

Yea I did mine this way and had to change it out to the lead going to the low pressure switch on the accumulator. It runs them all the time now no cycling.
I'm going to do some investigating and see if there is a way to have it cut off at speed to keep from having them on all the time.
I found this. Not sure I want to mess with it though!

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!
LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
