mirror wiring

Guys, I expect this has been beaten to death but I actually cannot find anything under search... does anyone have the OEM numbers for the electric folding mirrors which were an optional extra for the Astra J Gtc Biturbo? Cheers in advance!

Can anyone help? A boy racer caught my drivers wing mirror and broke the glass. I've got a new glass to fit on... but the 'box' contacts that should easily slot onto the new mirror are fowsty / gone coppery and I can't get the blessed things off the old damaged mirror. Are the plug contacts...
