CONNECTING THE INTERFACE
Follow these steps to properly install the interface module.
Step 1 - Remove the RADIO panel to gain access to the factory 20-PIN Harnesses. You will need to locate the CAN wire on the
vehicle. Page 2 will give you the full details on how to connect.
Step 2 - Using the provided 8-PIN Harness, you will need to connect the DATA Wire from the vehicle harness to the module, connect
the two YELLOW wires on the 8-PIN harness. See chart below for wire descriptions.

CONNECTING THE INTERFACE
Follow these steps to properly install the interface module.
Step 3 - Use the facotry 20-PIN connector to tap for DATA. Normally the 20-Pin connector will be GRAY and the CAN wire is located
on PIN 4 of the factory connector. Shown below is the WIRE VIEW (Solid Light Green)
Step 4 - You will need to cut the DATA wire in order to properly connect the module. With the wire cut, use the side coming from the car
to go to the INPUT (Yellow/Black) wire on the 8-PIN Harness. Connect the solid YELLOW back to the portion on the factory
connector. See diagram below.

CONNECTING YOUR DEVICES TO THE INTERFACE
Follow these steps to properly install the interface module.
Step 5 -The power for the module can be found on the GREEN 16-PIN connector. Located next to the GRAY connector.
RED = 12V CONSTANT / BLACK = GROUND (Make sure to measure the wires with a volt meter to confirm)
This same connection can be used to power the Wi-FI module, but you may want to take the location of your
factory AV Input location. Make sure your connections are long enough to reach all input connections.
Step 6 - Connect the 24-Pin AV Input/Output Cable to the Main Interface module. Connect the Camera and other Devices to the inputs
on this cable. See labels on the cables for descriptions. The AV outputs can be used to go to an external monitor.

CONNECTING THE Wi-Fi MODULE
Using the included Wi-Fi interface module make the following connections as recommended.
Step 1 - Connect the 10-Pin Harness to the Wi-Fi module. This cable will allow you the Audio/Video output for the vehicle.
Use the AV inputs on the WHITE 22-Pin T-Harness to connect the Wi-Fi AV outputs.
(See page 4 for details)
Step 2 - The interface does not provide you with a Power wire for the Wi-Fi module. Connect the RED wire from the 10-Pin Wi-Fi
harness to the connections used to power the main module. wire. For the best signal we recommend GROUNDING the Wi-Fi
module near the 12V Source. See Page 5 for more information.
