MK8 GTI/R Dashcam Hardwire Tap Install Guide

Remove the left kick-panel cover
Pull the lower left A-pillar trim panel away from the car body — it unclips with firm outward pressure. No glovebox or dashboard removal needed.
Identify Fuse F52
Locate the tall vertical fuse carrier in the lower-center of the fuse block and confirm which slot the fuse currently sits in.
Decide your wiring strategy
Ignition-switched: move F52 to the upper slot and tap the lower. Constant/parking-mode: leave F52 lower and tap the upper. For dual-wire kits, tap both per your kit's instructions.
Prepare the spade tap wire
Attach the inline fuse holder in-line on the positive wire. Keep the fuse as close to the fuse block as possible — not at the dashcam end.
Insert the tap into F52
Slide the add-a-circuit tap into the appropriate slot with a firm connection. Use a 2–5A fuse for the dashcam branch.
Connect the earth/ground
Remove the fuse box's end cover to expose a metal grounding stud. Clean it, then crimp and bolt a ring terminal to the dashcam's ground wire.
Route the wire to the dashcam
Run wires up the A-pillar behind trim, across the headliner, down to the mount. Avoid routing near yellow SRS/airbag connectors.
Test before closing up
Confirm the dashcam powers on/off as expected with ignition, and check for blown fuses or warning lights before refitting trims.
- Permanent live: fuse slot F22 (confirm unpopulated on your car first)
- Switched live: F52 lower position, same as LHD
- Earth: same end-cover stud method as LHD
- Verified on a MK8 GTI/R RHD build
