Hello people, Just thought i would post a comment about a future mod i have got planned. I wanna turn My Dials into a Digital display?

How hard would this be on a Vauxhall Corsa B

You want a Astra GTE dash into a Corsa. This is easy if you know which wires go where. Basically, get a digidash with the plugs with the wires cut off, cut the plugs off your analogue display and join the wires up. Most are colour matched, some are different, like 4, these are matched through trial and error.
If you want to be different get a digidash from a Carlton or a Senator.
