Many truck owners enhance their vehicles with aftermarket AMP PowerSteps for easier access. Typically, these steps are conveniently connected via an OBD2 plug. However, this method isn’t always ideal, especially if you’re already using your OBD2 port for devices like an Edge Insight monitor. Using a splitter can sometimes lead to irregularities and signal issues. Fortunately, there’s a more direct and reliable way to wire your AMP steps, eliminating the need for the OBD2 plug altogether.
This guide will walk you through bypassing the OBD2 plug and wiring your AMP steps directly using door jamb switches. This method offers a cleaner installation and avoids potential conflicts with other OBD2 devices.
The key to this alternative wiring setup is utilizing door jamb switches. These switches, when activated by opening the door, send a ground signal that triggers the AMP steps to deploy. This replicates the functionality of the OBD2 connection but through a dedicated circuit.
Here’s a look at the type of door jamb switch you can use for a factory-like install:
To implement this, you’ll need to connect these door switches to your AMP step controller. Instead of relying on the OBD2 signal, the controller will now respond to the ground signal from the door switches.
Refer to the wiring schematic below to understand how to connect the door switches to your AMP PowerSteps controller. Always verify the wiring colors for your specific controller model as they can vary.
By following this direct wiring method, you can ensure your AMP PowerSteps function reliably without occupying your OBD2 port. This is particularly beneficial for users who need their OBD2 port for diagnostic tools or performance monitors, providing a seamless and interference-free setup for your aftermarket running boards.
