If you need more power backing up all you need to do is remove the wire for the reverse light just below the counter shaft sprocket and ground it. You will lose the reverse light but will have full power backing up.

 

Is there any way you can just ground the reverse wire at the light? Just so I dont have to cut any wires.

 

you have to ground it at the switch and not the light. This fools it into thinking you are not in reverse and cuts out the limiter
