This instruction applies to the chassis listed below:
- Peterbilt 320
- Peterbilt 520
WI#: 3EC-GATEWAYMOUNT-BEHINDCURBSEAT
Purpose: Provide gateway mounting instructions when installing behind the curb side seat.
Details: The 3rd Eye gateway and backup battery box must be mounted to prevent damage to the gateway or the cabling as a result of gateway movement. Behind the curb side seat is the PRIMARY option when mounting the gateway in a cab over chassis with dual air ride seats. Before mounting the gateway seat travel and adjustment must be checked for clearance to prevent damage to the gateway or prevention of seat movement. Figure 1.1 shows how a gateway should mount directly to the wall behind the curb side seat.
