Hobbs pressure switch installation.
I just bought one of these to power my second fuel pump. It did not come w/ any instructions. I have the Full Blown housing and I have read through several threads and cannot find a definitive write up. Can someone who has a dual setup w/ the Hobbs switch please explain how to wire this up? Thanks.

About the Hobb switch,Is it possible to cut the Hobb and run the cable -that is connected to the Hobb- directly to ECU (Motec M800) and set a switch with map sensor on/off for activation?
I was thinking to activate on Motec a switch and open the second pump on 0 bar (14.5 psi) and up.
What do U think?

For future reference, the Hobbs switch completes the positive signal from your battery. The positive wire from the battery (with a fuse inline) goes to the switch and then from the other side of the switch to what you are powering. Thank you Mellon for the explanation.

the hobbs switch is used as a "relay" triggered by pressure.
