I have a straight truck with steerable lift axles that use a mechanical air switch to lift and lower them but I’d like to have them lift when the truck is put in reverse due to they steer backwards when reversing. How do I need to wire this into my reverser switch on the transmission? Thanks

Mine don't steer, I have a mechanical/electric valve in my tool box with a switch on my dash that I can flip to make them go up or down, might be something to look in to. The T handle you see is the manual operation.

Ok thanks I’m just looking for a valve to use that does this.
Gridaxe5588 Thanks this. -
You're welcome, I'm OTR Owner Operator in an Expedite Straight truck, the states of Florida and Michigan require the manual operation part so you can't cheat the weights but mine is hooked up to a factory option switch in my Cascadia so they would never know looking in my cab.
