    Best place to pickup fuel pump power

    I'm doing a swap that includes a complete ECU (Tec3R)and relay replacement. It's not PnP. I need to find the best place to provide power to the fuel pump. I've got replacement relays already in place. Does the fuel pump power come into one of the power blocks under the dash?

    I believe the stock wiring is fuel pump relay to fuse box to fuel pump. I'd like to get the fuel pump power after the stock fuse box as I've already got a fuse as well.

      Why not use the stock lead? IT is long.

        If your battery is in your trunk?

        There are two power leads from the trunk:
        one is fused smaller guage for ecu I believe
        one is for the starter

        Either tap off of the fused wire, or run a new setup (wire,relay,fuse)

        Or as trent said, use the stock lead
