(1) Connector location 15
Check the connector location 15 (1) as noted in Illustration 2.
If there is a circuit wire in connector location 15 (1), this procedure does not need to be performed.
Any circuit in location 15 (1) would be a system power circuit. If there is no circuit wire in connector location 15 (1), the Power Circuit Installation procedure needs to be performed.
Proceed to the Section "Power Circuit Installation Procedure" to connect an unswitched system power circuit to the harness connector for the switch.Power Circuit Installation Procedure

Typical cab harness connections in the right-hand console for the Transmission Gear Select Switch before rework
Illustration 4 g06221723
Typical cab harness connections in the right-hand console for the Transmission Gear Select Switch after the rework has been completed. Dashed lines indicate reworked wiring and connector additions.
Note: Harness and connector configuration of the machine may not match the typical schematic, but the connections to the Service Connector and the Transmission Gear Select Switch will be the same. Refer to Illustration 3 and 4.Follow the below steps to install the Power Circuit:
Label each wire segment of the 207-3814 Wire As (three-way splice harness) as a "308" circuit, using the wire labels.
On each of the two segments that has the socket terminated, install the wire and socket in a 155-2269 Connector Plug As (two-pin plug connector) that is part of the 155-2270 Connecting Plug Kit at pin location 2. Ensure that the sockets are fully inserted and locked in place. Install the wedge in each plug.
Install an 8T-8737 Seal Plug in each plug connector at the unused pin location 1. Set the splice harness aside.
At the right-hand console, remove the covers to the console to access the cab harness connector and the connection side of the Service Connector.

Pin out of the Service Connector as viewed from the rear connection side
At the rear connection side of the Service Connector, use a terminal removal tool to remove the yellow wire and pin at location (A). This circuit is the "308-YL" unswitched system power circuit. Refer to the service connector pinout Illustration 5.Removing the connector from the mount may provide greater access if needed.
Install the "308-YL" wire and pin in a 3E-3364 Receptacle (two-pin receptacle connector) that is part of the 102-8802 Receptacle Kit at pin location 2. Ensure that the pin is fully inserted and locked in place.
Install the wedge in the two-pin receptacle connector. Install an 8T-8737 Seal Plug in the receptacle connector at the unused pin location 1. Connect the two-pin receptacle connector to one of the two-pin plug connectors on the three-way splice harness. Ensure that the connectors are in the locked position.
Insert the wire segment of the three-way splice harness that has the pin installed in the service connector at the vacant location (A). Verify that the pin and wire are locked in the service connector. If the service connector was removed from the mount,
