Atari Badlands pedal issues

[BigCanTikiMan]

I been looking everywhere for badlands pedals cant find them anywhere. So i heard people using Road Blaster pedals but i got play around with the wiring. The Road blaster pedal has a potentiometer in it. i have it working but it is the opposite. When i press on the pedal it stops and when i let go it go's. Do i need to add another wire to it OR any good ideas will be a help?

badlands has 3 wires ground (to the pedal)/in/out

I figure it out.

Road blaster pedal has 4 wires. ground (green), potentiometer In (red), potentiometer out (White) and potentiometer ground (black).

Bad lands is 3 wires. ground (green), in (purple/red) and out (blue).

The grounds go together (Green wires). Then hook up potentiometer in (red) to the in (purple/red). Last potentiometer out (White) and potentiometer ground (black) need to be put together with out (blue).
