What Is This?

i think this may be a rev counter module i need to get my rev counter working on my omex 500/xu10j2te in my 205, as you can see it has 4 wires reading 12v, 0v ip and op. anyone know if theres a diagram avaliable for it as it looks like its made by a company rather than something someones knocked up. cheers.

I would hazard a guess that 12v = positive, 0v = ground/earth, IP = input from ECU and OP = output to tacho
