MECHANICAL ATTACHMENT OF SIT
Below are the envelop and mounting hole dimensions for the SIT.
ELECTRICAL INSTALLATION OF SIT
The Switch Interface Transmitter (SIT) has two 12 pin connectors. They are differentiated by insert color and are keyed.
Monitor control functions are present in each connector to accommodate double control boxes on the truck. Note that
the pin numbering scheme for each connector is different. Be sure to look at the pins on each connector to find the
location of each pin.
Note: Pins 11 and 12 of the black insert connector provide power to the SIT and must be connected to the vehicle
power supply. The voltage at the + COMMON pin on each connector is derived from this supply voltage.
The Gray insert connector can be left unused if dual monitor controls are not needed. Be sure to secure the SIT with the
mating connector and plugs if unused.
