Illustration 1 g06254344
(1) 542-5350 Control Harness As Required
(2) 542-5351 Control Harness As Required
(3) 542-5352 Control Harness As Optional
Plug the 542-5350 Control Harness As (1) connector "A" into an existing user supplied engine ECM harness.
Plug connector "C" into 542-5351 Control Harness As (2) connector "H".Note: The 542-5352 Control Harness As (3) can be used for greater distances. This requires mating connector "C" to connector "F" and connector "G" to connector "H".
Connector "K" of the 542-5351 Control Harness As (2) will connect to user instrumentation. The end user may remove connector "K" and terminate the wires to data acquisition RS232 instrument per Table 3 or may order and connect accessory parts listed in Table 2.RS485 "4 Wire" Signal Usage

(1) 542-5350 Control Harness As
Install resistor cap "E" to connector "D" of the 542-5350 Control Harness As (1).
Plug connector "A" of the 542-5350 Control Harness As (1) into the existing engine ECM harness. Plug connector "C" of the 542-5350 Control Harness As into connector "H" of the 542-5351 Control Harness As (2).Note: If using the optional 542-5352 Control Harness As, connector "C" mates to connector "F" and connector "G" mates to connector "H".
Connector "L" of the 542-5351 Control Harness As (2) will connect to user instrumentation.The end user may remove connector "L" and terminate to a data acquisition instrument per Table 4 or may order and connect accessory parts listed in Table 2.RS485 "2 Wire" Signal Usage
Note: If using the optional 542-5352 Control Harness As, connector "C" mates to connector "F" and connector "G" mates to connector "H".

Remove resistor cap "E" from connector "D" of the 542-5350 Control Harness As if installed. Plug connector "D" of the 542-5350 Control Harness As into connector "B" of the 542-5350 Control Harness As.
Plug connector "A" of the 542-5350 Control Harness As (1) into the existing engine ECM harness. Plug connector "C" of the 542-5350 Control Harness As into connector "H" of the 542-5351 Control Harness As (2).
Connector "L" of the 542-5351 Control Harness As (2) will connect to user instrumentation.The end user may remove connector "L" and terminate to a data acquisition RS485 instrument per Table 4 or may order and connect accessory parts listed in Table 2.Note: It is recommended but not necessary to keep resistor caps "E", "I", and "J" in place. Removing one resistor will change cable impedance from 40 ohms to 60 ohms. Removing two resistors will result in 120 ohms.
