So Gents,
Just bought this car, and was installing a stereo, when I discovered a control unit, plugged in under the steering wheel. My question is, does this thing have keyless or alarm, and how the heck to I tell if it is installed. The unit itself, is plugged in, and running to a cable, but I dont see any fuses for it?

How do I tell if its installed, before I order a fob for it?

Many thanks
