Before accessing the controller, be sure power has been disconnected to the system.
1. Turn off the external source powering the display sign.
2. Open the fuse block(s) in the display sign.
3. Wire harness connectors have ramp and clip features to hold the connector in place. If inserting
connectors, ensure the connector ramp engages with the corresponding mating features.
