Note: If vehicle is equipped with a Banks Tuner, disconnect the 24-pin connection between the factory 24-pin connectors and the Banks Tuner 24-pin connectors.

Figure 13 6. After confirming the locating washer is in the #5 location, install the switch through the 3⁄ 8” hole on the backside of the instrument panel. The alignment pin should rest in the 1⁄ 8” hole and with the switch fully rotated counter clockwise; the shaft’s flat side should be facing the steering column. Secure switch with internal tooth washer and nut. Snug the washer; be careful not to over torque the nut and damage the plastic threads. 7.
Section 3 Banks Brake Operation The Banks Brake has five (5) operating settings; HIGH, MED (medium) , LOW, OFF and FB (Foot Brake Activation). See Figure 14. Figure 14: Banks Brake Selector Switch Guide LOW strength setting achieves a lower level of braking force and is recommended for lightly loaded or unloaded vehicles. The LOW setting may also be used for daily driving. CAUTION: Using the HIGH setting with a lightly loaded vehicle will result in VERY aggressive braking.
The use of a Banks Brake does not increase the load capacity of your vehicle. Gross combined Weight Rating specifications should always be adhered to. The Banks Brake will allow you to slow your vehicle more effectively within your vehicle’s weight specifications. Operation/Driving Now that you are familiar with the features that are available with Banks Brake, it is recommended that you experiment with the various settings prior to using the braking features in a towing or extreme driving situation.
