Voltage limiter

I just got my new IVR3 limiter today. I was wondering, instead of disabling the ground or opening up the fuel gauge if I could just remove the G1 wire from the plug going to the Cricut board? It is the voltage limiter and the fuel gage feed wire. Then use this wire to power up the new limiter and then supply the 5 volts out of the limiter to the third post on the fuel gauge?
