Nothing special- today I disabled the TPMS warning light by disconnecting the wire in the dome light fixture because no-one is able around here to reset the old system - I installed sensors on the tire valves that send to a receiver that sits on the dash. Works great, keeps me up to date on actual pressures in all tires, and the dome lights still work - they're really kind of poorly set in the fixture to be honest. Had to fiddle with the one on the left quite a bit.
