The power wire runs to the left red screw in your fuse box. The signal wire runs to a 12 volt switched power. I used the green/yellow wire in my cig lighter. Find a good solid ground for the ground wire and the othe wire runs to the inline fuel pump. Also, you will need to ground the pump.
IMO, i would not use that relay, i had one fail on me when i was running 9psi. Me, along with others are successfully running these set-ups without the relay.
What you need to do then is..........run a wire from a 12 volt switch power to the pump and a ground and that is it.

Rep Power: 281 ok so all i need to do is basically get power to the inline pump, so i can hook the pump directly to an accesory so it comes on with ignition. so what im getting out of it is that is OK to have the pump on the whole time you are driving, cause i dont have a pressure switch. mabey ill just hook it to a switch in the cabin so i can turn it off and on.....basically its only used when the vac turns into pressure, and thats read by that vortech blue thing right? so when it senses boost it makes that fuel pump up the pressure?????

the little black box is a relay

your SF system should be marked "In " and "Out"
from the firewall to the "In" and from the "Out" to the fuel rail
