This is the correct replacement throttle pot assembly for the Merits Mini Coupe S539 and S549 mobility scooters. The pot (short for "potentiometer") is used to control the forward/reverse movement of your scooter. Your pot will come with the bracket, screws, and a "wig-wag" lever for control.
Note: You may need to reuse your scooter's old wiring harness in order for this replacement potentiometer to function properly.
