Connecting a JoyCon, GM Vehicles

Some people have contacted me asking if I can help them get their JoyCon EX working with their GM car. Although I do not know how to do this on all cars, this is what I did to figure out how to get it working in my 2004 Grand Prix GTP.

1. Go to:

2. Choose SWI-X and at the bottom choose NO Non-Pioneer / Rockford.

3. Choose your vehicle make from the drop down at the bottom of the page and click “Search Vehicles”

On the next page, click your vehicle model in the list.

Most cars have a small image of the harness connector that used to go into the radio. Below this look for a statement that resembles the following:

Connect the SWI-X ‘s Green wire to Pin A7 (Blue or Green) of the above connector. Connect Pin A6 (Pink or Violet) to Accessory +12V.

Reading this, I would then plug the black wire from the JoyCon EX into A7 and the white wire from the JoyCon EX into the A6.

Some sites tell you to apply +12V to the A6. In the case of our JoyCon this is not correct. We are measuring resistance to voltage supplied BY THE JOYCON not from the car.

Hope this helps others.

JoyCon 2004 Pontiac Grand Prix

Connecting a JoyCon to the radio harness on my car and reading through all the available material that I could find, I kept running into some problems with 12v going into the JoyCon instead of measuring the resistance. Here is how I connected my JoyCon EX to my steering wheel controls on the factory radio harness.

GM24 Radio ConnectorRemember, this connector is viewed from the pin side, not the wire side.

Connect the DATA (white) wire from the JoyCon into pin A6 and then the GND (black) wire from the JoyCon into pin A7.

JoyCon ConnectedMight be a little hard to see, but the yellow wire in my harness is connected to the white data wire, and my orange wire from the harness is connected to the ground of the JoyCon.
