Au falcon cruise control aftermarket or factory setup?
which is better or should i say easier to install
should i get the factory cruise control buttons for steering wheel..
and wire up an after market version to it..
anyone with any ideas would be greatly appreciated

Go for a factory unit mate, you can't beat them!

I know in the EF/EL, if they had ABS then the main loom was already there, not sure with the AU as mine has it as standard.

Either way, go through the hassle if need be and fit the factory setup.
