Just like the title says, im sure there are plenty of people, including myself that need pictures on how to do things. So what would the proper way be to wire in a hobbs switch with a relay? I think this would be very helpful to every one, thanks every one!

I think you just take the ground wire from the relay, run it to the hobbs switch, then to ground.

There ya go, I copied it into here. In this diagram the hobbs switch is controlling the second pump. When it hits the determined PSI of the switch it will complete the ground and turn on the second pump. The reverse happens when boost is pullled away, the pump will turn off.
