Yes definitely pin 30 to pin 30. As far as i can tell all the pins on both ends should match up 1 to 32... i checked a few at random with a meter.you have to be careful with pins 1 to 16 (first connector) with the orientation of the plugs .. its easy as to get it up side down! the plug from 17 to 32 (second connector)should have a locating key on both ends of the lead so its inpossible to get that one wrong... unless someone has removed it... as was the case on my Lectronamo when i got it.. and it had wires removed!!
