Installation Guide
1. Preparation
- Disconnect Battery: Locate your vehicle's battery and disconnect the negative (-) terminal.

2. Wire Color Code Reference
The IMPULSE wire harness uses standard EIA color codes. Match these colors to the corresponding wires on your aftermarket stereo's harness.

| Red | 12V Accessory/Switched Power |
| Black | Ground |
| Orange | Illumination/Dimmer |

| Violet | Rear Right Speaker (+) |
| Violet/Black | Rear Right Speaker (-) |
3. Connecting the Harness
- Take the IMPULSE wire harness and your aftermarket stereo's wire harness.
- Carefully match each wire by color and function. For example, connect the yellow wire from the IMPULSE harness to the yellow wire of your aftermarket stereo harness.
- Use appropriate connectors (crimp caps, solder, or heat shrink connectors) to make secure and insulated connections. Ensure no bare wires are exposed.
- Repeat this process for all corresponding wires. If your aftermarket stereo has wires not present on the IMPULSE harness (e.g., parking brake wire, reverse wire), refer to your stereo's manual for their connection.
4. Connecting to Vehicle and Testing
- Once all connections between the IMPULSE harness and the aftermarket stereo harness are complete, plug the vehicle-specific connector of the IMPULSE harness into the factory wiring harness in your Ford F-150.
- Connect the antenna cable to your new stereo.
- Reconnect Battery: Reconnect the negative (-) battery terminal.
- Test Functionality: Turn on your vehicle and test the aftermarket stereo. Verify that it powers on, plays audio from all sources, and that all speakers are functioning correctly. Check for proper illumination and any other features.
5. Final Assembly
- If all functions are confirmed, carefully tuck the wiring into the dashboard cavity, ensuring no wires are pinched or stressed.
- Mount the aftermarket stereo securely into the dash opening.
- Reinstall all trim panels that were removed.
Troubleshooting
- No Power to Stereo:
- Check the vehicle's fuse box for blown fuses related to the radio or accessory power.
- Verify the yellow (constant 12V) and red (switched 12V) wires are correctly connected and receiving power.
- Ensure the black (ground) wire has a solid connection.
- No Sound from Speakers:
- Confirm all speaker wires (white, gray, green, violet and their black-striped counterparts) are correctly matched and securely connected.
- Check the stereo's fader and balance settings.
- Ensure the stereo's amplifier remote turn-on wire (if applicable, usually blue) is connected.
- Stereo Does Not Retain Settings (Clock, Presets):
- Verify the yellow (constant 12V) wire is correctly connected and receiving continuous power.
