quickest and maybe cheapest is to buy one from the scrappies(i'd get yours aout and look for the wiring first though),peice of cake to take off and on.
BUT! watch out for the light it has a very delicate rocker switch on the back of it,and i never managed to get mine working on the cordoba iirc
about 15 quid i paid i think.mk4 polo/classic one fits also.
