Corsa B Speedo Wiring

Does anyone have a wiring diagram for a Corsa B speedo? i've got some plasma dials, but i need to wire them to the cars lights so that they come on when my lights are one.

IIRC the corsa dials have the wiring tracks external like nova ones? If so, why not attach the feeds for the plasma lighting to the ends of the tracks where the bulbs used to go?

failing this, run a wire from your sidelight circuit to run them

on the fitting guide that comes with them says that you need to cut power to the speedo lights (the back light) and fit it to the dials. I think it's so the back light doesn't show up on the dials.

yeah, so just take the bulbs out of their sockets (3 large one I think) and then you have the terminals to solder the plasma wiring to?

just easier for me to find the two wires and solder them lol

have you got the clocks out of the car? When you do you will find that unlike most vauxhalls the dials are clipped into a housing with the contacts sticking thru the back. Its quite difficult to get this plug out and actually get in with a soldering iron to do anything to it IIRC as I tried when i had mine!

If you do tho, simply test for a live on sidelights, I *think* its plain yellow or white
