Found these up under the dash on the left side on the steering wheel (Lt hand drive car) on my '84 GTV6. There are four wires associated with them that not all connected and one "ear broken" see pics. Can't find them any where on a wireing diagram. They are certainly aftermarket but for what? My car has a Tropic Air which I'm reinstalling but can't turn on yet. most of my dash is still out so don't want to continue until I know what these are and what they hook too as it is easier now to get to stuff than it will be later. They have four wires asso. with them: red, red/black, white, & black.
