Hi len,

Have you looked at the Classic Manual?
On page 40 of a recent Cl manual,  is a description of using Aux 1 & 2,  with some waveforms,  etc.  This should help get you started.

Hi looked in manual, but it does not give the wiring of the connector block in the classic, no indication if the two wires are positive or one neg and the other positive, dont want bto blow the unit by connecting a 12 volt positive in the wrong place!

Hi len,

In the latest Classic Manual,  on pp 46,  there is a pictorial diagram  --  Diagram 5,  that DOES show the Polarity of the two Aux connectors on the Classic PCB:
file:///C:/Users/OMX/Documents/MidNite%20Classic%20Manual-rev-1933-353693.pdf

This manual section also describes how to configure the PCB jumper blocks on that Classic board,  as well.

Does this not make sense ?

Later,   Vic
