How does the installtion go for these first three items in the above link? Is it simple plug and play or exstenive modification (aka) destroying my car. Iam sure the clock is simple, the gauge cluster and control unit? And are the control unit for the heater/ac bulbs replaceable? I have one that is out on the far left side on the unit.
