(11) Transmission oil pressure sensorWith the key start switch in the ON position, 24 volt power is supplied from the batteries via circuit breaker 14 to Power Train ECM (8) and via circuit breaker 7 to transmission oil pressure sensor (11). 24 volt power is also supplied to remote control switch (1) and interface control module (10).

(10) Interface control module (12) Relay 17 for parking brake N.O. (13) Relay 18 for first speed (14) Relay 6 for brake control (15) Relay 5 for service brake relay N.C. (16) Relay 4 for service brake relay N.O.When remote control switch (1) and the remote control parking brake switch on the transmitter are in the ON position, a signal is sent to receiver (9). Receiver (9) sends a signal to interface control module (10). Interface control module (10) de-energizes relay 17 for parking brake (12) .Connector contact 22 is connected to J2-60 of Power train ECM (8). Connector contact 38 is connected to J2-61 of Power Train ECM (8). A signal is then sent to Power Train ECM (8). Power Train ECM (8) will de-energize remote control parking brake solenoid 1 (2), parking brake solenoid 2 (3) and parking brake solenoid 3 (5) parking brakes will engage. Parking braking oil pressure switch (4) sends a signal to Power Train ECM (8). Power Train ECM (8) supplies 24 volt power to remote control brake light (7). Remote control brake light (7) will remain illuminated till the remote control transmitter parking brake switch is moved to the OFF position and the motion control lever is moved from the CENTER position.When the parking brake switch on the remote control transmitter is in the OFF position, the remote control transmitter sends a signal to receiver (9). Receiver (9) sends a signal to interface control module (10). Interface control module (10) will energize relay 17 for parking brake (12). Power Train ECM (8) will energize remote control parking brake solenoid 1 (2). Parking brakes are disengaged and service brakes are applied. When the motion control lever is moved from the CENTER position, parking brake solenoid 2 (3) and parking brake solenoid 3 (5) are energized. Parking brake oil pressure switch (4) sends a signal to Power train ECM (8). Power Train ECM (8) will release the service brakes and turn off remote control brake light (7)
