PARTS INCLUDED
STRAIN SENSOR CONNECTION
Plug the wiring harness connector labeled “SENSOR A” to strain sensor
connector A. Refer to the installation overview to identify which sensor is
sensor A. Repeat for sensors B and C, if applicable.
INSTALL WIRING HARNESS
Insert the threaded male connector on the connection harness onto the female connector on the back of the scale. Make sure to orient the connector properly so that the small cutout on both connectors line up. Once the connector has been pressed in, thread the collar into the scale until it is hand-tight.
SENSOR CONNECTION
CONNECTING TO POWER & GROUND
Connect the RED wire to a switched positive (+) power source and the BLACK wire to the chassis ground (-). There is an extension cable included to reach the proper power source. The required supply voltage must be between 9 and 32 volts DC. DO NOT connect directly to a battery or any constant power source, the gauge should be connected to a switched source so that it can be disconnected from power when not in use. Most users connect to the vehicle marker lights or auxiliary wire from the 7-way. It is very important that all wiring connections be made watertight. Connections that aren’t water tight can cause corrosion in wiring and cause the scale to lose power.
- Crimp each end of the wire into the connector with a wire crimp tool (tool not provided).
- With a heat gun or heat torch, heat the connector until it shrinks completely around each wire end. Make sure you do not burn the wire jacket.
- After all, connections have been made, heat shrinks the entire group of splices so that it seals on the outer jacket of both cables.
- This connection is for RS-232 communication (use is optional). Use the RS-232 connectors to connect the gauge to a telematics device that supports RS-232 communication. For more information about this feature, please contact Right Weigh technical support.
