Elevating Accessibility: The Professional Installation Guide for INEOS Grenadier Electric Side Steps

The INEOS Grenadier and Quartermaster are legendary for their high ground clearance—a dream for overcoming boulders, but a bit of a climb for daily entry and exit. To balance off-road capability with everyday luxury, a set of intelligent, automatic electric side steps is the ultimate upgrade.

At Plomor, our electric side steps are engineered to deploy instantly when a door opens and tuck away seamlessly when closed, preserving the vehicle’s rugged silhouette and essential ground clearance. This guide provides a deep dive into the installation, safety protocols, and long-term care of this premium accessory.


Why Choose Plomor Automatic Side Steps?

Beyond simple convenience, our system offers integrated features designed for the modern overlander:

  • Intelligent Deployment: Utilizing high-torque motors, the steps deploy in under 1.5 seconds upon door operation.

  • Stealth Aesthetics: When retracted, the steps sit flush against the chassis, protected from rock strikes and brush.

  • Safety Sensing: Built-in anti-pinch technology stops the motor if an obstruction is detected, protecting your family and your gear.

  • Luminous Path: Integrated high-intensity LED lighting automatically illuminates the step area, ensuring safe footing during midnight camp arrivals.


Comprehensive Vehicle Compatibility

Our system is precision-calibrated for the specific mounting points of:

  1. INEOS Grenadier (SUV)

  2. INEOS Quartermaster (Pickup Truck)


Step-by-Step Installation Walkthrough

Disclaimer: This installation involves automotive electrical systems. If you are not comfortable with 12V wiring, professional installation is highly recommended.

Phase 1: Preparation & Safety

Safety is paramount. Begin by wearing protective eyewear and gloves. Disconnect the vehicle’s negative battery terminal to prevent any electrical shorts during the wiring phase. Gather a complete set of metric wrenches, sockets, and trim removal tools.

Phase 2: Removing Factory Trim

Carefully remove the plastic side skirts by releasing the factory clips and screws. Store these in a secure place if you intend to revert to stock in the future. Clean the exposed frame rails to ensure a perfect metal-to-metal contact for the brackets.

Phase 3: Mounting the Heavy-Duty Brackets

Locate the factory-drilled mounting holes on the Grenadier’s frame. Attach the front, middle, and rear mounting brackets.

  • Pro-Tip: Apply a small amount of anti-seize lubricant to the bolts. Torque them to manufacturer specifications, but leave enough "play" for final alignment once the steps are attached.

Phase 4: Precision Wiring & Motor Connection

Route the weather-sealed wiring harness along the interior of the frame, avoiding heat sources like the exhaust system or moving suspension components.

  1. Connect the main control module to a stable power source and ground.

  2. Plug the motor leads from the steps into the corresponding harness connectors (Front/Middle/Rear).

  3. Secure all excess wiring with UV-resistant cable ties to prevent rattling on corrugated roads.

Phase 5: Testing & Final Adjustments

Reconnect the battery. Open each door individually to verify that the steps deploy and retract smoothly. Once confirmed, tighten all bracket bolts fully and reinstall the side skirts, trimming the plastic slightly if necessary for a custom-fit finish.


Troubleshooting & Maintenance for Off-Roaders

To ensure your steps survive the harshest environments, follow this maintenance protocol:

Common Troubleshooting

  • Steps Not Deploying: Check the inline fuse near the battery and inspect the ground connection for corrosion.

  • Noisy Operation: Usually caused by dried mud or gravel in the hinge mechanism.

  • LED Flickering: Inspect the plug-and-play connectors under the vehicle for moisture ingress; apply dielectric grease if needed.

Longevity Maintenance

  • Hydro-Cleaning: After a muddy trail run, pressure wash the pivot points of the steps to remove grit.

  • Lubrication: Every 6 months, apply a high-quality dry silicone lubricant to the hinge points. Avoid "wet" grease, as it attracts trail dust.

  • Hardware Audit: Periodically check the mounting bolts for tightness, especially after extended travel on washboard roads.


Final Thoughts

Upgrading your INEOS with Plomor Electric Side Steps is an investment in both style and functionality. It transforms the accessibility of your vehicle without compromising its "go-anywhere" DNA.
