Hey.. Im thinking of undertaking the fairmont dash conversion...

has anyone on here ever done it before and have you got any tips or guide on how to do it and parts i need etc..

and which wiring looms will i need to change? will i have to change the h looom or can i just change the dash loom?

also with the key programming at ford
if i was to use the original key thats programmed to the dash bcm of the fairmont would i have to still take my car to ford..?
thanks
