Connections to be made (cont.)
3.5mm jack - steering wheel control retention:
The 3.5mm jack is to be used to retain audio controls on the steering wheel control.
• For the radios listed below, connect the included female 3.5mm connector with
stripped leads, to the male 3.5mm SWC jack from the 6527 harness.
Any remaining wires tape off and disregard.

Brown/White wire of the connector. Then connect the remaining steering
wheel control wire, normally Brown/White, to the Brown wire of
the connector.
• Metra OE: Connect the steering wheel control Key 1 wire (Gray) to the
Brown wire.
• Kenwood or select JVC with a steering wheel control wire: Connect the
Blue/Yellow wire to the Brown wire.
Note: If the Kenwood radio auto detects as a JVC, manually set the radio
type to Kenwood. See the instructions under changing radio type.
• XITE: Connect the steering wheel control SWC-2 wire from the radio to the
Brown wire.
• Parrot Asteroid Smart or Tablet: Connect the 3.5mm jack into the

a third wire for ground, disregard this wire.
Note: After the interface has been programmed to the vehicle, refer to the
manual provided with the radio for assigning the SWC buttons. Contact the
radio manufacturer for more information.
• For all other radios: Connect the 3.5mm jack into the port on the radio designated
for an external steering wheel control interface. Refer to the manual provided with
the radio if in doubt as to where the 3.5mm jack goes to.

Installing the interface
It is highly advisable to read the following steps beforehand, to ensure a clear understanding of
what is to be expected. The following steps must be done in the order that they are numbered.
With the vehicle completely off:
Touchscreen display
1. Connect the 16-pin harness with stripped leads into port “B” in the touchscreen display.
2. Connect the 6527 harness to the wiring harnesses in the vehicle. Then insert the 6527
harness into port “A” in the touchscreen display. But do not install this harness until exactly
before step 1 of “Initializing the Interface”. This is a timed process
3. Connect the 4-pin harness with yellow RCA jacks into port “C” in the touchscreen display.
4. Connect the hazard harness into port “D” in the touchscreen display, and then to the wiring
harness in the vehicle.
5. Disregard port “E”, it will not be used in this application.
6. Port “F” is an update port for future firmware upgrades.
7. Locate the factory antenna connector in the dash and complete all necessary connections
to the radio. Metra recommends using the proper mating adapter from Metra.

Initializing the interface
Attention! If the interface loses power for any reason, the following steps
will need to be performed again.
1. Refer to step 2 of “Installing the interface”.
2. Press the push-to-start button to start the vehicle.
3. Program the kit:
a. Once the touchscreen display loads up, select the vehicle type; “Ram 2013-up”.
b. Wait until the radio comes on, and the touchscreen display shows
“SWC Configured”. This process may take up to 3 minutes.
Note: If the touchscreen display does not load up, or the radio doesn’t come on within 3
minutes, and/or the touchscreen display does not show “SWC Configured”, turn the vehicle
off and disconnect the 6527 harnesses from port “A” in the touchscreen display. Check all
the connections, reconnect the harness into the touchscreen display, and then try again.
4. Test all functions of the installation for proper operation, before reassembling the dash.
Note: The clock and compass in the driver’s information center will no longer be functional.
Final assembly
1. Secure the completed assembly into the upper dash using the factory hardware.
2. Reassemble the center console and dash in reverse order of disassembly.
