How to Hardwire Your Wefoka Dash Cam in RAV4: Step-by-Step with Photos
So you've got the Wefoka OEM-style 4K dash cam for your 2022–2025 Toyota RAV4. The plug‑and‑play harness that connects to your rearview mirror is convenient, but what if you want a completely hidden installation with no visible wires at all? Or maybe you want to enable parking mode (if you add a hardwire kit) or free up the mirror connector for other accessories. That's where hardwiring comes in.
Hardwiring your dash cam directly to the vehicle's fuse box gives you a cleaner look, frees up the 12V socket, and allows you to choose which circuits power your cam (ignition‑on vs. always‑on). In this comprehensive guide, we'll walk you through two proven methods for hardwiring your Wefoka dash cam in a 2022–2025 RAV4: fuse box tapping and mirror tap. We'll include detailed photos (placeholders to guide you), fuse diagrams, and tips from owners who've successfully done it.
🔧 What You'll Need
- Wefoka dash cam (front and rear units installed)
- Hardwire kit (if your Wefoka didn't include one, you'll need a 12V to 5V USB hardwire kit with low‑voltage protection if you want parking mode)
- Add‑a‑fuse (fuse tap) kits – at least two if you want both always‑on and switched power
- Fuses – 3A to 5A for the dash cam circuit
- Multimeter or test light – to identify hot sides of fuses
- Trim removal tools – to avoid scratching panels
- Wire strippers/crimpers – if you need to extend wires
- Zip ties and electrical tape
- Patience and a good flashlight
📍 Method 1: Hardwiring to the Fuse Box (Most Common)
This method involves running a wire from your dash cam down to the interior fuse box, located under the driver's side dashboard. It's the most flexible approach and works for all RAV4 trims.
Locate the Interior Fuse Box
In the 2022–2025 RAV4, the interior fuse box is located under the dashboard on the driver's side, near the OBD‑II port. You'll need to crouch down and look up—it's behind a plastic cover that you can remove by hand (no tools required). The cover usually has a diagram showing fuse assignments .
Identify Fuse Slots
You'll need two types of power for most hardwire kits (if you want parking mode):
- Constant (BAT) power – for parking mode or maintaining settings
- Switched (ACC) power – powers the cam when ignition is on
Based on owner experience and fuse diagrams , here are recommended fuse slots:
| Fuse Slot | Type | Amperage | Notes |
|---|---|---|---|
| P/OUTLET NO.1 | Switched (ACC) | 15A | Powers the cigarette lighter – only on with ignition |
| ECU-B NO.1 | Constant (BAT) | 10A | Always-on, for keyless entry etc. |
| DOME | Constant (BAT) | 10A | Interior lights – always hot |
| Empty slot (e.g., near TRUNK OPEN) | Check with multimeter | – | Can be used if it provides the right power type |
Important: Always verify with a multimeter or test light. One owner noted: "Test light or multimeter will tell you the hot side" . The hot side of the fuse slot should match the input side of your add‑a‑fuse to ensure proper circuit protection.
Install Add‑a‑Fuse Taps
Take your add‑a‑fuse taps. If you're using an empty slot, you only need to put the dash cam's fuse in the top slot of the tap. If you're piggybacking on an existing fuse, place the original fuse in the bottom slot and the dash cam fuse (3A–5A recommended) in the top slot .
Orientation tip: Before inserting the dash cam fuse, plug the tap into the slot (without the extra fuse) and check for voltage at the wire. If there's no voltage, flip the tap 180°—this ensures the tap is oriented correctly so that both circuits are protected .
Connect the Hardwire Kit
Your hardwire kit will have two or three wires:
- Red (or yellow): Constant 12V+ (BAT)
- Yellow (or red): Switched 12V+ (ACC) – some kits combine both into one if you don't need parking mode
- Black: Ground
Connect the red wire to the add‑a‑fuse from your constant fuse slot, and the yellow wire to the switched slot. Secure connections with crimp connectors or solder.
Find a Good Ground Point
Look for a bolt or nut attached to bare metal near the fuse box. A common ground location is the bolt above the brake pedal bracket . Loosen it, slide a ring terminal under it, and tighten securely. Ensure there's no paint or rust at the contact point.
Route the Cable to Your Dash Cam
Now you need to get the wire from the fuse box up to the rearview mirror area where your Wefoka is mounted. Follow these steps for a clean, hidden install:
- Tuck the wire behind the dashboard trim, heading upward toward the A‑pillar.
- At the A‑pillar, carefully tuck the wire behind the rubber door seal and then behind the pillar trim. You may need to gently pry the trim—it usually clips on and off.
- Continue along the headliner edge toward the mirror. The headliner is flexible enough to tuck the wire in without removing anything.
- Route the wire to the location of your Wefoka camera. You can use small adhesive clips if needed, but most of the wire can be hidden.
One owner noted: "I ran the wire behind the glove compartment and up the passenger A pillar and behind the windshield header trim" . The process is similar on the driver's side.
Connect to Dash Cam & Test
Plug the hardwire kit's USB or power connector into your Wefoka dash cam. Reconnect the negative battery terminal. Start the engine and verify that the camera powers on. If you connected constant power, the camera may stay on for a while (depending on your hardwire kit's settings) or immediately turn off with the ignition—this depends on your wiring choices.
Test the G‑sensor and recording functions to ensure everything works.
📍 Method 2: Mirror Tap (Simpler, No Fuse Box Running)
If you don't want to run wires all the way to the fuse box, you can tap power directly from the rearview mirror connector. This is the same connector the Wefoka plug‑and‑play harness uses, but hardwiring here can be even cleaner if you use a mirror tap kit.
Note: This method provides only switched (ignition‑on) power in most RAV4s, though some trims have constant power available as well . It won't support parking mode unless you also tap constant from elsewhere.
Remove the Mirror Cover
As you did for the Wefoka installation, remove the factory plastic cover behind the mirror. Slide it down and press the orange clips to release it . You'll see the mirror's wiring connector.
Identify Power and Ground Wires
Based on detailed analysis from RAV4 owners , the 10‑pin mirror connector (often called P1) has the following pinout:
| Pin | Wire Color | Function |
|---|---|---|
| 1 | White/Green | 12V Switched (ignition on) |
| 2 | White/Black | Ground |
| 6 | Red | 12V Constant (BAT) |
| 9 | Purple | CAN High |
| 10 | White | CAN Low |
For basic operation (cam on with ignition), you want pins 1 (switched) and 2 (ground). If your hardwire kit needs constant power for parking mode, you could also tap pin 6, but be careful not to overload the circuit—use a multimeter to verify amperage capacity.
Use a Mirror Tap Kit or Solder
You can purchase a pre‑made mirror tap kit (like Dongar or similar) that plugs inline with the factory connector. However, note that some adapters may not pass through CAN bus signals correctly if they're not pinned properly—you may need to move pins 4/5 to 9/10 if using a generic adapter .
Alternatively, use Posi‑Taps or carefully solder wires to the back of the connector pins (on the vehicle side). Many owners successfully tap the white/green (switched) and white/black (ground) wires with Invisicord or similar taps .
Connect to Dash Cam and Test
Route the wire from the mirror area to your camera (usually just a short distance). Connect to your Wefoka, start the car, and confirm it powers on.

❓ Frequently Asked Questions
Q: Do I need a special hardwire kit for Wefoka?
A: Wefoka typically uses a USB‑C or Mini‑USB power connection (check your model). Any quality 12V to 5V hardwire kit with the correct connector will work. If you want parking mode, choose a kit with low‑voltage protection to avoid draining your battery.
Q: Which fuse slots are empty in the 2022 RAV4?
A: It varies by trim and options. Some owners report empty slots near TRUNK OPEN or WASHER that can be used . Always test with a multimeter to confirm if they're constant or switched.
Q: Can I use the mirror tap for constant power (parking mode)?
A: Yes, pin 6 (red wire) is constant 12V in many RAV4s . However, be mindful of the circuit's current capacity—most mirror circuits are only rated for a few amps, so a dash cam (usually <1A) should be fine. Use a fuse tap to be safe.
Q: What amp fuse should I use for the dash cam?
A: 3A to 5A is typical . Never exceed the rating of the original fuse slot.
