Thank You for your help 'Daox'
I think I've sorted out the problem now ...
Pg 4 of the Curtis 1204/1205 manual helped quite a bit with the Black/Blue/Pink colours that were confusing me ...
Blue is the common ...
Black & Orange(pink) are the 0-5 or 5-0 ohm for the pot box ...
There is a separate micro switch which is not wired as far as I can see ...
On the Curtis PMC foot pedal pot box on Pg 5, Fig 4 ... the Black & White are the 0-5 ohm for the pot box, with the Blue & Orange the micro switch, and Green not being used ...
This was just a 'cheap' ($48.99) Chinese PB-6 with no instructions on colour code with a micro switch not wired in ...
I think maybe that was the colour of wire they had handy ...
Maybe I was having a 'seniors moment' ... but it confused the HELL out of me for awhile ...
Thank You Again
