The following steps will walk you through how to correctly mount and install the gauge. 1 CHOOSE MOUNTING LOCATION The gauge can be mounted in the dash panel either using an existing factory gauge hole or by creating one. If this option is unavailable or not desirable, Right Weigh has an optional bracket (202-BR) that can be purchased separately to mount the gauge. See below for a detailed list of options for mounting into the dash: a Use an available 2 1/16" (52mm) factory gauge hole. b Remove and replace a factory installed drive axle air suspension pressure gauge. c Cut a new hole in the dash panel using a 2 1/16" (52mm) hole saw as shown. Make sure to check behind the dash ! panel for internal wires and components that may need to be moved to avoid damage. d Use Right Weigh 202-BR bracket or an aftermarket bracket to mount the gauge. 6 SCALE INSTALLATION & ELECTRICAL CONNECTIONS 2 INSERT 202 GAUGE Insert the gauge into the mounting hole or bracket. Hold the gauge in a position so the display appears level on the dash panel or bracket. Note that the thickest portion of the gauge bezel indicates the bottom of the display. Screw the gauge nut onto the back of the gauge until it is tight. INSERT TIGHTEN 3 INSTALL BEZEL STYLING COVER (OPTIONAL) If desired, place chrome styling cover over the front of the gauge bezel. Press until both sides snap into place. 4 CONNECT TO POWER AND GROUND Connect the wiring harness to power and ground. Be sure the RED wire is connected to a SWITCHED positive (+) power source (DO NOT CONNECT DIRECTLY TO BATTERY) and the BLACK wire to chassis ground (-). Supply voltage must be between 9 and 32 volts DC. DO NOT connect directly to a battery or any constant power ! source, gauge should be connected to a switched source so that it can be disconnected from power when not in use. Most users connect the power to the ignition switch. Connect the wire harness to the connector on the back of the gauge. 5 DUMP AIR FROM SUSPENSION SYSTEM 7 SCALE INSTALLATION & ELECTRICAL CONNECTIONS 6 INSTALL NEW STREET TEE FITTING Remove the suspension air line fitting from the top of one of the air bags.

Yes No To reset the gauge back to the factory default settings, select YES. 20 TROUBLESHOOTING PROBLEM CAUSE SOLUTION Erratic / Inaccurate Weight Readings The vehicle is not parked on Park on level concrete ground. Parking on sloped or banked a level surface surfaces will cause the vehicle weight distribution to shift between the axle groups. Additionally, if one or more of the vehicle's wheels are in a pothole, that could result in additional pressure or torque on the suspension air bags. This will cause the suspension to have a different air pressure than what is noramlly needed to hold up the given weight. The vehicle's brakes are on Release the parking brakes when weighing and/or calibrating. When the vehicle brakes are set, they could apply additional pressure or torque on the suspension air bags. This will cause the suspension to have a different air pressure than what is normally needed to hold up the given weight. There is a significant air leak Check air lines for leaks. Having a leak could cause the HCV to in the suspension system refill the suspension at regular intervals to maintain the vehicle's ride height. If there is a significant leak, the gauge display will slowly decrease in value and then quickly increase in value when the HCV refills the suspension system. The Height Control Valve (HCV) is malfunctioning or broken If the HCV is not functioning correctly, the air pressure applied to the suspension system could be inconsistent and/or erratic. To test for an HCV problem, acquire a weight reading from the Right Weigh gauge and write it down (refer to gauge operating instructions for proper procedure). Drive the vehicle around the block and return to the same location. Acquire a second reading from the Right Weigh gauge. If the two readings are significantly different, then the HCV might be malfunctioning. Scale Does Not Power Scale is not connected to a On switched power source of between 9 and 32 VDC Connect the scale to a switched power source between 9 and 32 VDC (typically either the vehicle marker lights or the AUX/ABS wire). If there is a bad connection in the circuit which causes voltage to drop below 9 volts, the scale will not power on. Test the power source with a voltmeter. Cannot Change Calibration Data Scale is connected directly to the battery Polarity is incorrect The scale has an active user-defined security PIN code Connect the scale to a switched power source between 9 and 32 VDC (typically either the vehicle marker lights or the AUX/ABS wire). The scale is active anytime it is connected to power, even if the display is off. To reset it, disconnect and reconnect to the power source, wait 10 seconds, then try again to turn the display on. Correct the polarity. The red wire must be connected to positive and the black to negative. If the scale is protected with a PIN code, the PIN must be entered before calibration data can be changed. To understand how to reset the PIN code, see page 16. If the PIN code has been forgotten, please call Right Weigh technical support listed on page 2 for further assistance. Gauge Will Not Calibrate Low/High Air pressure in the system is To enter low or high cal mode, the gauge must see a measurable not changing change in air pressure. Make sure you calibrate high when the vehicle is near the legal limit and calibrate low when the truck is empty. Also, be sure the air line is connected directly to an air bag - NOT the main air supply or brake system. 21 APPENDIX A The following is a list of additional parts needed for air line installation.
