It is a three pin connector with a silver label that says KS or similar. ! IMPORTANT ! ONLY use the white microphone connector on the bluetooth harness! The bluetooth harness also has a black plug for the optional RF compensator (booster) that could also fit although it should be taped down to the harness to prevent accidental connection.

Pairing Procedure

The pairing procedure that must be initiated through the phone will differ corresponding to the different menu configurations of the various Bluetooth mobile phones on the market. The user’s manual of the phone should always be referenced for specific steps on how to activate the Bluetooth feature and to pair/link devices.
The following steps are generalized steps that should help in activating the Bluetooth function of most phones:
IN VEHICLE:
1. Depress the pairing button for at least 1 second prior to switching on the ignition and continue to hold the button down for
approximately 2-3 seconds after the ignition is turned on.
2. Release the button.

ON PHONE:
1. Locate the connection/settings menu and select Bluetooth
2. Select the response that will activate the Bluetooth feature of the phone.
3. Next select a menu option that will allow you to “Discover” or “Search” for active Bluetooth devices.
4. If the phone identifies/finds a device select it and follow the indicated steps to complete the pairing process which will include the request for the Bluetooth passkey. The Bluetooth passkey is the sticker you removed previously and is also on the ULF module parts label.
5. Once the phone is successfully paired to the device cycle the ignition switch off and back on and the devices should wirelessly connect within 30 seconds. When the connection is established the phone will display a connection symbol.
