Looking at the din socket, up into the arm, there are 5 pins if you numbered the pins starting from the lower left and going round clockwise it would be as follows;-
1-red Right signal
2-Green Right ground
3- arm ground black if its in a linn TT it should have a short lead for the ground in the turntable and a long one to go to your Phono stage
4-White Left signal
5- Blue Left ground
check with a multimeter from head shell to plug and plug to phono stage
