need autometer rail pressure gauge wiring info

[GFB]

Bought a used gauge and can't locate the instructions online. Looks like two wires connect to the factory rail pressure signal wires. Anybody know which ones go to which? What's the easiest location to tie into the signal? Thanks a bunch.

ill give you a hint, if you hook them up the wrong way, they wont work. its only 2 wires coming from the RP sensor harness
