Racetronix Harness / MSD Pump Booster
Has anyone here used the racetronix fuel pump harness with the msd pump booster 2351? All the racetronix install info I can find is for a pump booster with only 2 or 3 wires while this one now has 4....it has 2 reds (one to battery 12, one to factory fuel pump harness power wire), orange to fuel pump and ground. I'm curious what they do with the second red wire...I assume since the racetronix harness replaces the factory harness you can leave out the +12 battery line and just connect the one but I'm not sure. They don't seem to maintain their support forum anymore.
