Sourcing a replacement E46 Steering wheel airbag plug

[Harding91]

Long story short i bought a ropey E46, aftermarket steering wheel fitted and whoever did it instead of wiring in a resistor and wiring up the horn decided to just snip the wires and live with the light on the dash.

I'm planning to keep the aftermarkett wheel on as its likely to end up a track car, however id love a horn and the airbag light not to be on.

Where can i find a replacement plug? Looks like this :




I can always pop to a scrappy and grab one but idealy would like to just order one on ebay or whatnot.
