Ramp truck aux battery wiring

Here is how I ran my aux batteries for the winch.

I bought the cables from Harbor Frieght and ran the red one from the battery up front to my 12 volt contactor under the truck. Then the black one to the aux batteries in my case. I also have a air compressor hooked to the contactor through a relay.
The contactor is controlled by a dash mounted switch to charge the batteries and fill the tank up with a pressure switch to shut it off at 120lbs. Having the aux batteries hooked this way will not kill the truck battery for starting the truck.
But if the need arises for the aux batteries to start the truck then I can.

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.
