Try not to laugh...
I bought this tacho on eBay the other day. its a fair bit older than I expected it to be... looks like it could be older than I am! But anyway, it should be good for what I need it for, so long as someone could tell me what the connectors on the back are, and where I need to connect them.
Just so you know what the front looks like:
I've figured out that the two that come off the thing that sticks out the back are for a backlight, which should be simple to set up. The other three, however... could someone please help me with these?
There's some writing on the side of it... the part that most makes sense goes: "12V 993-1660 Hz" The word "justierbar" is below that - it's made in Germany. Oh wait, the three prongs are marked! One's got a "+", one's got a "-" and the other has a "G". Fair enough... so where do I connect them? My Stanza doesn't have a tacho atm.
