GXYWADY's 19-04280-STA replacement controller restores automated AMP Research power running board operation for vehicles using A-04/A-06 style modules.

If your AMP Research power step stopped responding or you need a direct-fit modern replacement for older A-04/A-06 controllers, this GXYWADY 19-04280-STA unit is built to match the original mounting and wiring locations while delivering reliable control for electric running boards. The unit ships with a matching wiring harness and user manual for straightforward installation, so you can return your retractable steps to consistent, vehicle-linked operation.

How does this controller restore running board function?

The GXYWADY controller takes over the electronic commands that open and close AMP Research power steps, reading door and ignition signals and driving the motorized mechanism accordingly. It replaces legacy A-04 and A-06 modules so the steps behave like the factory system once again.

• Direct replacement for A-04/A-06 and legacy 19-04280-ST* controllers
• Includes matching wiring harness to connect to existing connectors
• Plug-and-play orientation and mounting locations mirror OEM units

What comes in the box and what will I need to install it?

The package arrives with a pre-programmed running board control module, the corresponding wiring harness, and a user manual that outlines wiring and mounting steps. Basic hand tools are normally all that’s required; professional installation is recommended if you’re not comfortable with automotive electrical systems.

• 1 x GXYWADY Running Board Control Module (19-04280-STA)
• 1 x Matching wiring harness with OEM-style connectors
• 1 x User manual with wiring diagrams and mounting tips

Will this controller work with off-road use and vehicle clearance needs?

Yes — by restoring proper retraction control, the module helps ensure running boards stow fully when clearance is required during rough terrain driving. Proper operation reduces risk of snagging and helps maintain ground clearance when the boards are not in use.

• Restores automatic retraction to lower snag and damage risk
• Supports normal open/close sequencing tied to door and ignition signals
• Durable electronic enclosure designed for under-vehicle locations

What vehicles and legacy controllers does this module replace?

This replacement is intended for vehicles using AMP Research running boards that originally shipped with A-04 or A-06 style controllers, and it also replaces earlier 19-04280-STA/STB generations. Confirm connector compatibility and mounting footprint before installation to ensure fitment.

• Compatible with AMP Research power steps using A-04/A-06 modules
• Replaces legacy part numbers including 19-04280-STA and 19-04280-STB
• Check harness and connector shapes against your OEM controller
