Follow these steps to install your IMC Audio Radio Wiring Harness:
- Prepare the Vehicle: Disconnect the negative terminal of your vehicle's battery. Remove the factory radio from the dashboard, following your vehicle's specific instructions.

- Connect to Aftermarket Radio Harness: Match the color-coded wires of the IMC Audio harness to the corresponding wires on the aftermarket radio's wiring harness. Typically, aftermarket radio harnesses come with a wiring diagram. Ensure each wire is securely connected (e.g., by soldering and heat-shrinking, or using crimp connectors).
