Right, are they all the same from base model to GSi? Or do they vary. This may sound a silly question it's just that Sean McManus has just fitted a Cav Turbo trip computer in is Cally 16v. Apparently they go straight in. Vauxhall use one common loom and it's just a matter of finding which wires go where.
Is this the case with the MK3 Astra?
I want an Astra GSi comp in my Cabrio using an Omega saloon stalk.
