I'm afraid not. IIRC the signal ABS/Cluster is digital not a straight ground or 12v, but don't hold me to that. It can be programmed out by Ford WDS, but they charge anything up to £100 just to connect up.

I think the ABS is an LED soldered into the PCB; I've known it to be blocked with chewing gum on s/h cars !

Taking the brake bulb out leaves you without hand brake/low fluid warning, but then again you haven't got that if its on because of ABS.
