Hello, I bought a maganfuel pump and there dual relay. I need a wiring diagram of how to wire it up.

I was thinking of setting it up like this. Pin 85 goes to ground with hobbs switch spliced into it. Pin 86 to alternator or battery. Pin 87 with 30amp fuse to alternator or battery. Pin 30 to positive side of fuel pump. Is this correct, or does it need to be changed. Thanks in advance.

Terminal 30 gets a fuse and should be connected to the battery/alternator. Terminal 86 goes to the signal source(stock fuel pump power wire, switch, whatever is telling the pumps to turn on). Terminal 85 to ground with the Hobb switch in line. Terminal 87 goes the the fuel pump positive post.

Can I hook up terminal 86 to the battery also, or does it have to be to a 12v signal? Thanks for the help

What you have here is 100% correct as long as when you say "Hobbs switch spliced in, you mean that the Hobbs switch is in series with the ground. I prefer to power pin 87 at all times over 30 so you don't have a hot sitting on 87a at all times for no reason.

Awesome, and yes, I meant the hobbs switch in series. Thanks Bret.
