If the Pyrometer Interface Harness connector is a 70 pin, Route 517-0586 Engine Harness As to the Pyrometer Harness Interface connector and install Red wire into position 70 and the Black wire into position 69. If the Pyrometer Interface Harness connector is a 40 pin, install the Red wire into pin 1 of a 2-pin receptacle and the Black wire into pin 2. This connector will then connect to G-C3 of 514-3813 Engine Harness As.
With the engine powered, use a digital multimeter to verify that 24V power is present at the Pyrometer Harness Interface connector.Installation of 510-4068 Electronic Control Gp (Pyrometer)
Attach 489-3081 Harness As to 510-4068 Electronic Control Gp (Pyrometer) and the Pyrometer Interface Connector. Using 489-3081 Engine Harness As as a gauge, temporarily install the module on an appropriate place as per the choice of installer.Installation of 505-1731 Engine Harness As
If the engine under test is a 16 cylinder instead of a 20 cylinder, 505-1731 Engine Harness As can be installed between 489-3081 Engine Harness As and 510-4068 Electronic Control Gp.Installation of 489-3081 Engine Harness As
Perform the following procedure to install 489-3081 Engine Harness As:
Install 504-3341 Engine Harness As on the service port connector of 489-3081 Engine Harness As.
Route 504-3341 Engine Harness As to a safe location before performing tests.Note: Attach 140-9442 "Y" Adapter Cable As in order to see all the machine ECMs. Connect 504-3341 Monitor Harness As to "Y", connect other leg to Machine Service port and the third leg to Communication Adapter.Overview and Configuration On Caterpillar Electronic Technician (Cat ET)
