Wiring question
 

I have a 2002 Mini Cooper S that I just completed a major service (clutch, AC compressor, condenser, belt, hoses, supercharger). I have a two-wire plug with Blue/Yellow and Green/Red wires. For the life of me I cannot find where this plugs into. I am getting an ABS warning light and a low tire pressure warning light. The wires come out of the harness near the thermostat.

Any help would be appreciated
