For Ford truck owners enhancing their vehicles with AMP Research Powersteps, the standard installation often involves plugging directly into the OBD2 port. While straightforward, this method isn’t always ideal, especially for those already utilizing the OBD2 port for devices like the Edge Insight monitor. This guide explores how to wire AMP Research Powersteps directly to your Ford truck, bypassing the need for an OBD2 plug and offering a cleaner, more integrated setup.
The conventional AMP Research Powersteps installation leverages the OBD2 port to communicate with the vehicle’s computer system. This connection signals the steps to deploy and retract when doors open and close. However, users who already have devices like performance monitors or diagnostic tools occupying the OBD2 port often resort to OBD2 splitters. Splitters can sometimes lead to communication issues or signal degradation, potentially affecting the performance of both the Powersteps and other connected devices. Furthermore, some users simply prefer a more direct and less cluttered wiring solution.
Fortunately, AMP Research Powersteps can be wired to function correctly without relying on the OBD2 port. The solution lies in tapping into the door trigger circuits of your Ford truck. By connecting the AMP Research controller to the door switches, the Powersteps can be activated based on door operation, mirroring the functionality of the OBD2 connection but through a dedicated wiring setup.
The fundamental principle behind this method is utilizing the door jamb switches. These switches, which activate the interior lights when a door is opened, can also serve as triggers for the AMP Research Powersteps. When a door opens, the switch grounds a specific wire, signaling the AMP controller to deploy the steps. Conversely, when the door closes, the ground is removed, and the steps retract.
To implement this OBD2 bypass, you will need to identify the correct wires for the door trigger circuits in your specific Ford truck model. Wiring schematics, like the one provided below, are invaluable resources for this process. These diagrams detail wire colors and locations, ensuring you tap into the correct circuits. It’s crucial to verify the wiring diagram relevant to your year and model, as wire colors can vary between Ford truck generations.
Door Jamb Switch for AMP Powersteps Wiring
The wiring process involves connecting the door input wires from the AMP Research controller to the corresponding door switch wires in your truck. This typically involves splicing into the door trigger wires. Always ensure you are making secure and insulated connections to prevent shorts or electrical issues. Refer to the wiring diagram provided by AMP Research and your Ford truck’s service manual for precise wire identification and connection points.
AMP Powersteps Wiring Diagram to Bypass OBD2 Plug
Choosing to bypass the OBD2 plug for your AMP Research Powersteps offers several advantages:
- Free up OBD2 Port: Allows for simultaneous use of other OBD2 devices without splitters.
- Eliminate Potential Conflicts: Reduces the risk of communication issues associated with OBD2 splitters.
- Cleaner Wiring: Creates a more direct and potentially cleaner wiring setup, avoiding reliance on the OBD2 port as a central hub.
- OEM-like Integration: Mimics the function of factory-installed running boards that are triggered by door operation, without OBD2 dependency.
While the standard OBD2 plug installation is convenient, directly wiring your AMP Research Powersteps to the door switches provides a robust and potentially more reliable alternative. By understanding the wiring principles and utilizing the correct schematics, you can achieve a seamless integration of your Powersteps, freeing up your OBD2 port and ensuring optimal functionality. Always consult with a qualified automotive electrician if you are unsure about any aspect of the wiring process.
