Reference: Special Instruction, SEHS9615, "Servicing DT Connectors"

Two new horns are available as service replacements for the following horns:

• 7T-0969 Horn

• 7T-0970 Horn

These new service replacement horns feature an integral sealed connector for improved corrosion resistance.

The 163-1201 Horn and the 174-7875 Horn service replace the 7T-0969 Horn and the 7T-0970 Horn on the serial numbers that are listed above. Refer to Table 1.

Installation Procedure

Illustration 1	g00819233
163-1201 Horn (1) Integral sealed connector

Illustration 2	g00819945
174-7875 Horn (2) Integral sealed connector

1. Turn the keyswitch to the Off position. Open the disconnect switch.

2. Disconnect the two machine harness wires that are connected to the existing horn.

3. Remove the ring terminals from the two machine harness wires that were just disconnected from the horn.

4. Crimp a 186-3736 Connector Socket to each of the two machine harness wires.

5. Insert the two Connector Sockets (that are crimped to the two machine harness wires) into the 155-2270 Connecting Plug Kit. For instructions on inserting the 186-3736 Connector Sockets into the 155-2270 Connecting Plug Kit, refer to Special Instruction, SEHS9615, "Servicing DT Connectors". After the sockets have been installed into the connector, tug on the wires in order to ensure a secure connection.

6. Mate the machine harness with the new horn's integral sealed connector (1, 2). Check for proper operation of the horn.
