Add a support and mount the Alltrax SR controller on the driver side of the cart.
From the local Lowes or Home Depot get a 3ft Piece of 1.5 x 1.5 aluminum angle metal.
Trace and drill 2 holes in the cart frame for the Alltrax control where the resistor coils were mounted.
Measure & cut the 1.5 angle so it can support the other side of the controller and bolt to the main frame on each side as shown.

Mount the solenoid on the cart's vertical support on the passenger side of the cart just behind the batteries and the half-way underneath the seat opening as shown. For clarity note the motor location and see the new cross-member install below the solenoid
