Audi A1 / Q3 Rear Tail Light Plug (Pre-Wired): Pin Order, Fitment Checks & Installation
Swapping rear lamps or repairing a damaged plug? A pre-wired connector speeds the job and avoids reusing heat-hardened housings. Use this checklist to get pin order, sealing and strain relief right the first time.
Before You Start
- Confirm the plug keying visually against your lamp module.
- Note wire colours and functions on your car before cutting the old plug.
- Have loom tape, heat-shrink and a quality crimp tool ready.
Installation Steps
- Disconnect battery or disable rear lighting circuit.
- Label the old wires by function (tail, brake, indicator, reverse, earth).
- Join the pre-wired leads to the vehicle harness using proper open-barrel crimps or sealed butt splices.
- Add strain relief and route the harness to avoid sharp edges or standing water.
