Default MSPNP With Water/Meth

Hey Everyone, I'm about to install a water/meth injection system and I noticed that there are settings for it in megasquirt. I'm assuming one of the wires that I'm not using from the harness will simply turn on when the criteria are met. I would love to wire this to my relay instead of using an external pressure switch but I have no idea which wire to use.

Anyone know?

The firmware is kind of one size fits all, but the water/meth hardware is not installed in an MSPNP. You probably could make it work but would really have to know what you're doing with a soldering iron.

Matt- looks like he's just looking to flip a relay on at a certain boost pressure, is there not an unused output he can use to do this prewired? If not, it's probably just a jumper wire out of the box and a wire to your relay to use an unused output to drive it...
