Most likely a problem with the black wire - this goes to an ignition live so when the ignition goes off, it turns the MFD off

I have put a multi meter on the constant live =12v
Switched live = only 12v when the ignition is on
Headlight wire = only 12v when the headlights are on
Illumination wire = only 12v when the headlights are on
But my clock is light up constantly. Could it be a problem with the clock rather than the wires

Does anyone have the pinout for the mfd on a corsa c, or are they the same, my combo has one fitted (didnt originally) and my mate has tapped in to the feeds from the headunit but it doesnt switch on with the ignition, needs a switched feed, but i have no idea which wire needs the feed (ive not looked thoroughly at the pinout on page one as im guessing a C will be different?)

Please feel free to call me a plum if ive missed it or the plugs are both the same lol!

Hey AJ, did you ever get the MFD rev counter chip working?
I still use a corsa b MFD in my 91 Panda 4x4.

Lol, I'm tempted to try and fit one to my MX5!
