Upgrading to an electric tailgate is one of the most practical ways to modernise your vehicle. Whether you drive a ute or SUV, a power tailgate retrofit adds convenience, safety, and a premium feel.
But how do you actually install one?
At Auto Retrofit , we’ve created this step-by-step electric tailgate installation guide to help Australian drivers understand the process—whether you’re going DIY or considering professional installation.
⚠ Before You Start
Installing an electric tailgate is moderately complex and involves electrical work.
You’ll Need:
- Basic mechanical tools (spanners, screwdrivers)
- Trim removal tools
- Routing tools (or similar cable guides)
- Electrical knowledge (basic to intermediate)
- 2–4+ hours of time
👉 If you’re unsure at any step, it’s best to contact a professional installer.
Step 1: Check Vehicle Compatibility
Before purchasing or installing, confirm your vehicle supports an electric tailgate kit.
Key Checks:
- Tailgate structure and mounting points
- Electrical system compatibility
- Available space for motorised struts
👉 At AR Australia, we provide a vehicle compatibility list to make this easy.
Step 2: Disconnect the Battery
Safety first.
Always disconnect your vehicle’s battery before starting to avoid:
- Electrical shorts
- Accidental airbag triggers
- Damage to onboard systems
Step 3: Remove Interior Tailgate Panels
Carefully remove the interior trim of your tailgate.
Tips:
- Use trim tools to avoid scratches
- Keep clips and screws organised
- Take photos for reassembly
This step exposes the internal structure for installing components.
Step 4: Install the Electric Struts
Replace your existing gas struts with motorised electric struts.
Important:
- Ensure correct left/right placement
- Secure mounting points tightly
- Avoid twisting or misalignment
These struts are the core of your electric tailgate system.
Step 5: Mount the Control Module
Install the control unit inside the tailgate or rear panel area.
This Module Controls:
- Opening/closing motion
- Sensor input
- Remote/key signal
Make sure it is:
- Securely mounted
- Protected from moisture
- Properly connected
Step 6: Route the Wiring Harness
This is the most technical part.
You’ll Need to:
- Run cables from tailgate to vehicle body
- Use factory wiring channels where possible
- Avoid pinching or bending wires
👉 Clean wiring = reliable performance
Step 7: Connect to Power & Vehicle System
Connect the system to:
- Vehicle battery
- Ground point
- Central locking system (if required)
Important:
Incorrect wiring can:
- Damage electronics
- Cause malfunction
- Void warranty
Step 8: Install Control Buttons & Sensors
Depending on your kit, install:
- Tailgate open/close button
- Dashboard switch
- Optional foot sensor (hands-free access)
Position them for easy access and usability.
Step 9: Reassemble Panels
Once everything is installed:
- Refit interior panels
- Secure all clips and screws
- Ensure no loose wiring
Step 10: Test & Calibrate the System
Reconnect the battery and test the system.
Check:
- Smooth opening/closing
- Proper height adjustment
- Anti-pinch safety function
- Remote/key operation
Most systems allow you to set tailgate height memory—perfect for garages.
Common Mistakes to Avoid
❌ Incorrect Wiring
Can damage your vehicle’s electronics
❌ Poor Alignment
Leads to uneven lifting or motor strain
❌ Skipping Calibration
Reduces performance and safety
❌ Rushing the Install
Take your time—precision matters
