Working on my 73 3.0 CS: I had the dashboard speaker out today and noticed a relay behind it with wires unplugged (previous owner unplugged it, i guess). It's a silver hella, and it says "Summer" on it. One of the wires in is hot (12V) and one is not. It's not truly a relay since it only has two plugs (one in and one out). Any ideas what this is for? I have searched forum and haven't found anything...
