Thank you for the input
. I finally figured it all out. I was making it way to complicated at first.
The toyota switch I used was for fog lights fro an earlier model I think. I ran it through the relay included with the ARB wire harness. Seems to work great and the system is holding air. I connected the solenoids to the rotary switch and hooked a couple relays up to the diff lock ECU plug so the diff lock dash lights work also. Now I just need to wrap and route the wires to finish it off.
