I think it has the same wiring. You replace the regular cruiser control switches with the ACC switches. It has a plug that does into where regular CC plug goes into. They basically dont have a dedicated wiring going into the BCM or ECM, it just connects to a plug on the steering wheel. Below are the diagrams for both modules;Don't expect there to be the plug for the ACC in the wheel. The car will most likely have a different harness. This means you will need to get the wiring diagrams and wire it up yourself. You will also need the male and female pins, and the male connector plug that goes into the ACC switch.
You will be adding the missing wires from the switch to the clockspring, and then from the clock spring to wherever the wiring diagrams say - probably the car's main computer module and the cluster.
It is not hard. I've done this sort of thing many times retrofitting equipment and functions to my other cars. But don't expect to just pop in the switch, as I am 99% sure there will be nothing to plug it into.
