Many Ford truck owners enhance their vehicles with aftermarket AMP Powersteps for easier access. These retractable steps often utilize an OBD2 plug for their operation. However, this can present a problem when you want to use other OBD2 devices, like performance monitors such as the Edge Insight. Using a splitter might seem like a solution, but it can sometimes lead to irregularities and is not ideal. Fortunately, there’s a way to wire your AMP steps without relying on the OBD2 port at all.
The most effective method to bypass the OBD2 plug for your AMP steps involves wiring them directly to your vehicle’s door switches. This approach uses the door switches to trigger the deployment and retraction of the steps. When a door opens, the switch grounds a wire, signaling the AMP steps controller to deploy the steps. Conversely, closing the door removes the ground, causing the steps to retract. This method provides a clean and reliable installation that doesn’t interfere with your OBD2 port, allowing you to use devices like your Edge Insight without issue.
To implement this, you’ll need to identify the correct wiring for your AMP steps controller. Wiring colors can vary, so always verify the specifics for your model. The principle remains the same: you’re looking to connect the door trigger wires from your AMP steps controller to the door jamb switches. This setup mimics the functionality of an OEM installation, providing a seamless user experience without the need for the OBD2 plug.
While some might consider using a Ford controller and splicing into the CAN bus system, this is generally unnecessary and potentially problematic for aftermarket AMP steps. Aftermarket AMP step motors are different from OEM motors, particularly in how they sense deployment. Therefore, the door switch wiring method is typically the preferred and simpler solution for integrating AMP Powersteps without an OBD2 plug.
The wiring diagram below illustrates a typical setup for connecting your AMP Powersteps controller to the door switches, effectively bypassing the OBD2 port. Always double-check your specific wiring diagrams to ensure compatibility and correct connections for your vehicle and AMP steps model.
By choosing to wire your AMP Powersteps directly to the door switches, you ensure uninterrupted use of your OBD2 port for other devices and achieve a clean, integrated installation. This method avoids potential conflicts and provides reliable operation of your aftermarket running boards.
