I am trying to work out the wiring on a H6ZBME-5P Cosmicar/Pentax lens they are as follows:-

2 White---- 2 and 5 loosely shown linked like this [
5 Blue ---- + 12v Near
4 Green ---- 4 and 6 loosely shown linked like this [
6 Red ---- + 12v Tele
7 Orange ---- Pot Supply
8 Grey---- Pot Return
3 Sky Blue ----Wiper Focus
1 Pink ---- Wiper Zoom

So I am assuming 2,5,4,6 and 7 are all 12v +ve and 8 is -ve
Pins 3 and 1 go to the respective outputs from the control board
It's a bit confusing if the above is correct why did they not connect 2,5,4,6 and 7 internally! or am I reading it incorrectly? Thanks,
John.

The answer is using the common connection on the control board join 5 and 4 together use 2 to the focus connection and 5 to the zoom the rest are not used unless you are using feedback to a telemetry monitoring system :wink:
