How to find the pin-numbers?

All you need is a DVM with Resistance Measurement and a small copper wire (with un isolated ends). The rest is precise work. To get the correct pin i used my digicam to photograph the wire, zoomed into the picture on my display and counted if the wire is placed correct. Then with the DVM you can find the corresponding pin on the other side.
