Default MSD 2350 Pump Booster Wiring Help

I bought it used a while back and finally getting around to installing it along with the Racetronix harness. I've got the red wire coming from the relay plugged into the fused orange wire of the booster and the red output wire from the booster plugged into the downstream red wire going to the pump (which I believe is correct per MSD's instructions). What am I supposed to do with the two black wires coming out of the booster since I am using the Racetronix harness? Just run these to a common ground?

You should be able to ground both of them but if that doesnt work for some reason you would just run the smaller black wire to the negative terminal on the fuel pump plug.
