For truck owners looking to enhance their vehicle with AMP Research Powersteps, the standard installation often involves plugging directly into the OBD2 port. While convenient, this method can sometimes present limitations, especially if you’re already utilizing your OBD2 port for other devices like performance monitors or diagnostic tools. This article explores an alternative wiring approach that allows you to install your AMP Research Powersteps without relying on the OBD2 plug, offering a cleaner and more flexible setup.
Why Consider Bypassing the OBD2 Plug?
The OBD2 port in your vehicle is a valuable interface for accessing vehicle data and running diagnostics. Many enthusiasts use OBD2 devices such as the Edge Insight monitor mentioned in the original forum post to keep track of engine parameters and overall vehicle health. When your AMP Research Powersteps system also requires an OBD2 connection, it can lead to:
- The Need for Splitters: Using an OBD2 splitter can introduce potential points of failure and clutter in your vehicle’s cabin.
- Potential Interference: While generally safe, some users might experience irregularities or conflicts when multiple devices are connected through the OBD2 port.
- Desire for a Cleaner Install: For those who prefer a more integrated and less intrusive installation, bypassing the OBD2 plug offers a streamlined solution.
Direct Wiring: An Alternative to the OBD2 Plug for AMP Research Powersteps
Fortunately, AMP Research Powersteps can be wired directly into your vehicle’s electrical system, eliminating the need for an OBD2 connection. This method utilizes door trigger switches to activate the power steps, deploying them when a door opens and retracting them when closed.
Utilizing Door Trigger Switches
This approach involves tapping into your vehicle’s door jamb switches. These switches are designed to activate interior lights and other door-related functions when a door is opened. By connecting your AMP Research Powersteps controller to these switches, you can achieve seamless operation without the OBD2 plug.
The forum post provides a helpful image of a door jamb switch, illustrating a typical installation point for such a setup.
These switches provide a ground signal when the door is opened, which can be used to trigger the AMP Research Powersteps controller. It’s crucial to verify the wiring specifics for your particular AMP Research controller model as wire colors and configurations can vary.
Wiring Diagram for OBD2 Bypass
The following wiring schematic, also sourced from the forum discussion, outlines the connections required to bypass the OBD2 port and wire your AMP Research Powersteps directly.
Key points from the diagram:
- Power and Ground: You will need to connect the AMP controller to a 12V power source and ground in your vehicle.
- Door Trigger Wires: The diagram indicates wires for door trigger inputs. These are the wires that you will connect to your door jamb switches. Ensure you identify the correct wires for your specific vehicle and AMP controller.
- Controller Specific Wiring: Always refer to the wiring documentation that comes with your AMP Research Powersteps kit. Wire colors and functions can differ between models and vehicle years.
Important Considerations:
- Verify Wire Colors: Double-check the wire colors on your AMP Research controller and your vehicle’s wiring harness before making any connections. Wiring mistakes can damage your system or vehicle electronics.
- Professional Installation: If you are not comfortable working with automotive electrical systems, it is highly recommended to seek professional installation from a qualified technician.
- OEM Motor Incompatibility: As mentioned in the original forum, aftermarket AMP step motors are different from OEM step motors and are not interchangeable. This wiring solution is designed for aftermarket AMP Research Powersteps installations.
Conclusion: A Flexible Installation for AMP Research Powersteps
Bypassing the OBD2 plug for your AMP Research Powersteps installation offers a valuable alternative for truck owners who want to avoid OBD2 splitters or potential interference. By utilizing door trigger switches and direct wiring, you can achieve a clean, reliable, and seamlessly integrated power step system. Always prioritize safety and accuracy when working with vehicle electrical systems, and consult professional help if needed to ensure a successful and safe installation of your AMP Research Powersteps.
