Ground Bolt
CONNECT WIRE 229-BK-18 TO GROUNDConnect wire 229-BK-18 to ground. Refer to the machine schematic for a proper location to attach to ground. An excellent ground location is at an existing machine grounding bolt that requires no splicing. Refer to step 7 for suggested connection and for splicing techniques.
CONNECT WIRE 403-GN TO ALTERNATOR R-TERMINALConnect wire 403-GN to the alternator R-terminal circuit. You can connect directly to the R-terminal on the rear of the alternator, or you can connect to a convenient connector in the R-terminal wiring circuit. There will be either a 11 to 32 V square-wave from 0 to 2 KHz or a steady DC voltage equivalent to the battery present on this connection. Refer to step 7 for suggested connection and for splicing techniques.
CONNECT WIRE 308-YL-18 TO SWITCHED POWERConnect wire 308-YL-18 to any source of battery power that is controlled by the keyswitch. Refer to the machine schematic for a suitable location to connect to switched power. Most Caterpillar schematics are colored to indicate the circuits that receive power when the keyswitch is ON. It is not recommended to splice into the MAIN key switch circuit if another circuit is available. Refer to step 7 for suggested connection and for splicing techniques.If the machine has a CAT data link, proceed to Step 12. If the machine does not have a CAT data link, proceed to Step 13.

Example Of Splice Into CAT Data Link Wires At Existing Service ConnectorIf wires are removed from their connectors, the wires must be terminated. The wires cannot be exposed to power or ground. (1) Existing Service Connector (2) Existing Twisted-Pair CAT Data Link Wires (3) Added 4-Pin Connector (4) Product Link Wiring Harness Datalink Wires (THESE WIRES MUST BE TWISTED)Note:
CONNECT WIRE 893-GN-18 AND WIRE 892-BR-18 TO CAT DATALINKThe two wires that connect to the CAT data link must be spliced into the existing CAT data link wires. The positive CAT data link wire 893-GN-18 is spliced into the existing positive CAT data link wire. On most machines this wire is 893-GN. On some machines, this wire is 944-OR. The negative CAT data link wire 892-BR-18 is spliced into the existing negative CAT data link wire. On most machines this wire is 892-BR. On some machines, this wire is 945-BR. Refer to step 7 for suggested connection and for splicing techniques.Note: All CAT data link wires are twisted pairs. When you splice the new Product Link wires into the data link, ensure that the two wires are also twisted. The wires should be twisted from
