when i bought my car, it came factory with the steering wheel controls and Audiopilot (volume raises with the engine).

i bought the swi-ps but i cant find the plug that has the swc wire, all i know is its a white wire, so my question is..

since the car has steering wheel controls and audiopilot, is it possible that the VSS wire and SWC wire are in the radio harness, since they had to be connected to the stock radio to work? Thanks!!

the wires should be there, but it depends on the vehicle. what do you have? only thing, if its a gm then those are most likely in the LAN system.

its an 05 RX-8

the peripheral interface should have come with a yellow sheet with a web address for specific programming instructions. go to that site and put in your car info and itll give step by step install instructions and programming for your car. sorry i dont have a link for it at home....its all at work. same with the vss info.
