FAQ

What is the 79105-01A?

It is an AMP Research PowerStep manual-override accessory with the controller requirements and included components listed above.

Does this kit include a controller?

Yes. It includes an STA controller, override switch and wiring harness. It is not the switch-only option for a system already equipped with a compatible dual-plug controller.

Which existing controllers is this kit intended to replace?

The current manufacturer listing identifies single-plug A-04 and A-06 controllers. Read the label and compare the connector arrangement before selecting the kit.

Can I select it from my trucks year and model?

No. The installed PowerStep system and controller generation determine this accessorys compatibility. A vehicle fitment list does not identify which controller is currently fitted.

Will it work with every PowerStep kit?

No. The manufacturers installation guide excludes kits 75134-01A and 75141-01A. Check the exact installed kit and controller before ordering.

What do the three switch positions do?

They select manual retraction, normal door-operated automatic use, or manual deployment. Keep people and objects clear while the boards move.

Does manual mode remain selected indefinitely?

No. The manufacturer states that automatic operation returns on the next door cycle after 30 minutes. Account for that reset when cleaning or servicing the system.

Does installation require electrical work or drilling?

Yes. The instructions require harness connections and switch mounting in a suitable panel. Inspect behind the panel before drilling and follow the exact guide for the installed system.

Installation Instructions

1. Identify the PowerStep kit and installed controller; compare the exact instructions before disconnecting components.
2. Isolate the systems electrical supply as directed and inventory the supplied switch, harness and any controller retrofit parts.
3. Follow the kit-specific connector and controller procedure. Do not interchange STA, STB or SSA wiring arrangements.
4. Choose an accessible panel location, inspect behind it, and drill or route wiring only as specified in the guide.
5. Secure wiring clear of moving or hot parts, restore power and test retract, automatic and deployed operation.

Read the manufacturers installation guide.
