Installation: The kit plugs directly inline with your factory left handlebar up/down. The large green 10-wire matching connector goes up front under the front frame rail, then plug in the shift motor to the matching kit factory stock plug. Connect the battery to the correct terminals. Converts the ES system into a manual electric shift-controlled transmission, functioning the same as a foot shift model with the ease of the touch of a button for an "on-demand" shift style. A great alternative for older electric shift ATVs equipped with computer-controlled ESP systems that require expensive or unavailable parts, or for vehicles with oversized tires or gear reduction that may confuse the shift computer and speed sensor, preventing the stock computer from allowing shifts. Only requires a good battery, shift motor, and up/down shift buttons on the left handlebar control.
