The throttle sensor on your golf cart is a significant feature. Its operation allows you to communicate the position of the accelerator pedal to your controller. The controller then interprets that signal and allows a metered amount of voltage to reach the motor. This is what allows for smooth acceleration. On your caddie, it is called a Club Car Precedent 2nd Generation MCOR Three. Club Car is currently on their 5th generation of this throttle, but the one you need is based on the year of your golf cart. This model was used on the precedent models only that were 2012 and newer. The MCOR One worked for 2004-2008 models. Then you had the generation to that fit 2008 through 2011. You could also get a conversion to make this one fit the older models.This golf cart MCOR is a replica of the one that is on the cart. It will bolt right onto the accelerator pedal sub-assembly. You do not need an additional pigtail; this will plug right into the harness. Get with Buggies Unlimited on this today.
