airbag control: gauge panel or switch box??

[Irishpilot]

I'm unclear on what is the best setup for manually controlling 4 airbags independently (aka each wheel seperately). I don't want ride control sensors, or any of the automatic stuff; just gauges and switches/rockers that allow for me to change pressure.

I've looked for a gauge panel that has four rocker switches, and three gauges (2 dual needle for airbags, and one single needle for tank px), but I haven't seen one. A lot of companies, including SSD, sell switch boxes with up to 10 switches. What are these used for and where do you keep the switch box?

Right now I'm kicking around a few avenues of approach. Any help would be greatly appreciated!
