I am trying to replace the throttle pedal control on a 1995 Parcar. I ordered a part that was told would work as a replacement however it is different than what was on the cart and it came with no instructions. The new part is called a Pot box with switch and I need to know how to wire it up. I am attaching pictures of the old and new part so you can see what the difference is. The first photo is the original and the next two are different views of the new one. Thanks for any help.
