Greedy data link wiring
 

Hi can anybody help me please. I bought a Greddy oil pressure and oil temp data link gauges off a forum but have found out the POWER leads for the data link units are missing. If anybody has a Greddy data link unit could they have a look at the orange plug and tell me what colour goes to each pin. There are 6 pins but i think only 5 are used. The power lead looks like this if i could see the back of this one i would be ok lol
