I just did this myself, used a programable piece from a company called Mcpii.com, just splice 5 wires. Works great, can program 3-5 flashes. I'm not sure how much the OEM retrofit is, or how it wires into the harness, but this was around 70 usd (about 50 quid) shipped to me. The thing to remember is that the facelift D2 has two flasher/turn signal relays, and the one needed to tap is under the driver side dash.
