Default Need help with Walbro inline wiring

I picked up a Walbro inline pump (255 lph) from a board member, and need help with the wiring of it. I know I need to mount it between the tank and the fuel filter, and I assume I just splice into the plastic fuel line back there (is that correct?). The real issue I have is that I do not know the wiring schematic for it. I have the relay, but really don't know what goes where to make it active when the stock pump is running. Also, what is the best source of power for the pump? I read that I should not run them off of the same direct supply, so where should I get the power from?

If anyone can post up a wiring diagram for me as to what runs from the relay and where it goes I would really appreciate it. I have searched on here and LS2, and have had no luck in finding this.

Thanks
