Locate vehicle plug from Programming Radio Commands page and use this page to find the pin location and wire color (if any).

All SWC wires can be located at the factory plug behind the radio, unless instructed to find elsewhere.

General Motors

GM5: Pin#1, org/blk wire.

GM7: Pin# 6 or 7, green wire. In some vehicles the location of the wire will be in a 15-pin connector.

GM21: Pin# 14 or 13, dark blue or light green wire, newer 2002 vehicles might be purple/blk. In some early 1990's vehicles, the wire maybe in a separate 7 pin connector. If doing front and rear controls, tie both pin# 14 and 13 together and connect to SWI-X, connect pin #12 pink or purple to 12v accessory.

GM24: Pin# A7 blue wire. Connect to green wire of SWI-X. Pin# A6 pink wire, connect to12v accessory. If factory radio is relocated, be sure that the blue and pink wires are not connected to the factory radio.

GM32: Pin location E5, dark blue or light green. In some vehicles this wire maybe In location E6 or E16.

GM32 HVAC: Locate light green wire in pin# E5 (in some vehicles, pin# E6) and connect to green wire of SWI-X. Locate dark green wire in pin# E1 and connect to blue wire of SWI-X. Note: For some Buick vehicles, the light green and dark green wires maybe in a separate 7 pin connector.

Trailblazer-Bravada-Envoy: Locate 17-pin plug (part of main ignition harness underneath dash at steering column), connect SWI-X to the Lt. green wire in A 12. Cut brown loop wire on SWI-X and insulate. Do not use orange wire on SWI-X.

Cadillac (except Catera and Escalade): Locate 40 pin connector on left side of the steering column below the dash. Connect SWI-X green wire to the dark blue or It. green wire in D8. If the Cadillac has HVAC controls, cut the brown loop wire on the SWI-X and insulate. Program for ‘Version 1'. Do not use orange wire on SWI-X.

Ford

Ford2: Pin# 2. Wire color maybe tan, pink/wht, Lt. blu/red or Lt. blu/blk

Ford16: Connect Lt. grn/blk (pin# 3 or pin# 5) to 12 volts accessory. This supplies power to buttons on steering wheel or rear controls. Connect Lt. blu/pink (pin# 16 or pin# 12) to orange wire of SWI-X.

Ford20: Pin# 15 or 14, Lt. blu/red or yel.

Ford-Dual: Vehicles with both steering wheel and rear controls. 2 separate interfaces are required If both front and rear controls need to be used together.

Front steering wheel = Version 3: Ford20, connect pin#15 or 14, Lt.blu/red to white wire of SWI-X.

Rear center console = Version 6: Ford20, Connect pin# 5 to 12 volts accessory. This supplies power to the rear controls. Connect pin# 6 to orange wire of SWI-X.

Chrysler

Chrysler, Dodge and Jeep Vehicles: You must intercept the SWC wire at the steering column and NOT at the radio harness plug. Remove the steering wheel column cover around the ignition key cylinder and locate wire in white or gray plug.

1999-2002 Grand Cherokee: red/yel wire.

2000 Prowler: red/blue wire.

1999-2000 Ram/Dakota/ Durango: red/blk wire.

1999 Town & Country: red/blk wire.

2001 Ram/Dakota/Durango/Caravan: gry/wht wire.

2002 Jeep Liberty: red/blu wire

Dodge Ram: Red/Blu.

IMPORTANT!  1999 and newer vehicles: First verify that you have the correct wire with a voltmeter. Voltage readings should vary between 0-5v for each button pressed. You must cut the wire in half after the correct wire is identified. Attach the SWI-X white wire to the SWC wire coming from the white or gray plug.

1992 -1998 All vehicles: These vehicles have been confirmed to always be a blk/org wire. Cut blk/org wire in half and connect SWI-X green wire to the SWC wire coming from the white plug.

Insulate remaining wire going dawn into the dash. Do not use the orange wire on the SWI-X.

Imports/Misc.

Acura/Honda16: Pin# 12, wht/blu. Acura/Honda20: Pin# 3.

Audi/VW20: Pin# 11, Audi – wht/yel; VW  - color varies.

BMW16: 97-99 Connect SWI-X to pin# 7; 2000-01 you will need to cut the wire at the steering wheel column and connect the SWI-X yellow wire to the steering wheel side. Wire colors vary; please verify wire in steering wheel column with the wire in pin# 7 of factory plug. Note: Cars with factory activated cellular phones are not supported at this time. Some 97-99 vehicles may have to be interfaced at the steering wheel column like the 2000-2001 vehicles.

Harley-Davidson: These have a separate wire for each button and do not have a resistor in line. When testing for these wires, each button will show close to zero ohms for each respected wire. Locate a separate plug with these wires and connect a resistor to each wire starting with the lowest value first. Connect all resistors remaining leads together to the SWI-X. Download wiring diagram from website.

Jaguar20: Locate purple/yel wire on factory 20-pin plug. Cut purple loop wire on SWI-X and connect 1500-ohm resistor in line of purple wires. Mazda14: Pin# 8

Mitsubishi6: Locate yel/wht wire in separate 6-pin plug from factory radio.

Nissan (excluding 1999-2000 Quest): These vehicles have a separate wire (except vehicles below) for each button and do not have a resistor in line. When testing for these wires, each button will show close to zero ohms for each respected wire. Locate a separate plug with these wires and connect a resistor to each wire starting with the lowest value first. Connect all resistors remaining leads together to the SWI-X. 2001 Maxima: brn/wht, gm/blk, yel/red, blu/yel, red.

2002 Maxima and Altima: Connect a 150-ohm resistor on the (Maxima - blu/yel) (Altima -green) wire and a 47-ohm resistor on the (Maxima - red) (Altima - red/wht) wire. Connect remaining end of resistors to the white wire of the SWI-X. Connect the (Maxima - brn/wht) (Altima - blue) wire to chassis ground.

Land Rover: Locate 2 wires from steering wheel control buttons that plugged into factory radio. Normally they are gray/red & gray/black. Connect the gray/black to chassis ground and the gray/red to the white wire of the SWI-X. 2002 Freelander: connect blk/red to ground and blk/wht to SWI-X white wire.

S2000: On Acura/Honda20 plug, connect pin# 3 to the white wire of the SWI-X. The mute button supplies 12v on a yel/blu wire in pin#14 and latches on and off. Do not connect this to the SWI-X. If the aftermarket stereo has a "mute" input, use a relay to invert the yel/blu wire to a negative output and connect to the mute input of the stereo. If the mode button on the dash does not work properly, connect a 3.6k to 4k ohm resistor across the white end black wire of the SWI-X and re-program.

Saab: Tap into yel/blk wire in 22-pin connector of the SID display module. Cut violet loop wire in half on SWI-X and insulate separately.
