The Aprilia 2D000203 headlight wiring harness is the cable bundle that powers the headlight for the RSV4 1000, RSV4 1100 Racing Factory, and Tuono V4 1100. In the official Aprilia catalog, it is position 5 on the headlight diagram. It carries power and ground to the headlight through two relay sockets and a series of waterproof connectors: when the low beam or high beam flickers off, or following a fall that tore the fairing, it is almost always here that something has broken.
✓ Key features
- Original Aprilia part number 2D000203: OEM lengths, connectors, and routing.
- Pre-installed connectors: no splicing to be done, no wires to strip.
- Two integrated relay sockets, just like on the stock harness.
- Covers three V4 families: RSV4 1000, RSV4 1100 Racing Factory, and Tuono V4 1100.
- Alternative to manual repair: a harness patched up with tape and splices is the primary suspect for any future electrical failure.

⚠️ Important notes
- This item is the harness only: headlight unit, bulb, and hardware are not included. Relays do not appear in the replacement part photos — if you need those as well, please write to us before ordering.
- Always disconnect the battery negative terminal before working on the electrical system.
- Photograph the routing of the old harness before removing it: there is little space on the V4 fairing, and routing matters.
- If the headlight continues to behave erratically with the new harness, also check the relays and the ground on the front subframe.
Who it's perfect for
For those who have an RSV4 or Tuono V4 with a flickering headlight, or for those who have repaired their bike after a slide and found the headlight wiring torn. It is the spare part that avoids the need to buy the entire lighting assembly.
