Thank you Xfire it seems the wire is the "Fused Traction System Relay Output" (Red/Green), this should help me trace it back to where it should connect, the diagrams are spot on, much appreciated.

Pioneer: Yes I checked all aspects of the K40 as thoroughly as I could, I even used the microscope at work, I couldn't locate any of the often cited issues such as bad solder, charring, and the relay when exposed did 'seem' to switch between on/off when the car was started and functions were operated, I confess my knowledge is limited I'm trying to educate myself through certain literature and of this site which quite frankly is bloody amazing. Seems to be a great community on here so far.

Thank you.
