### Step 1 - Run the Power and CAN Harness

The ECU harness includes 2 sets of Power and CAN Cable. Depending on the model year of your car, you'll connect the power, ground, and CAN Bus in different locations:

#### **For Variant A (Intel)**

Refer to **"Method 1 - Power & CAN Connection on Intel MCU"** from the following guide.

#### **For Variant B (AMD)**

Refer to **"Method 3 - Power & CAN Connection below Right A-Pillar"** from the following guide.

### Step 2 - Connect the LVDS Cable

Remove the bottom cover on the passenger side (FRONT RIGHT for LHD cars / FRONT LEFT for RHD cars). It is secured by 3 push pins.

### Step 5 - Set Up the System

You need to test the dip-switch settings before tidying up the trim pieces.

Try Setting 1 first and see if you can click the CarPlay icon. If not, try setting 2, hold the scroll wheels on the steering wheel for 15 seconds to reboot the car and test again.

Please notice that PIN 8 is used to set LHD / RHD option.
