Hello, are you having any issues with the controls on the steering wheel? Here's some wiring diagrams that show the controls, wire colors, and what they go to. Plus the steering wheel angle sensor Circuit (pic 1). Pic 2 is the cruise control switch without Distance control feature. Pic 3 is the cruise control switch with Distance control switch. Pic 4 is the Laser sensor circuit for distance control. Pic 5 is the Radio mode and volume buttons. The wiring for the switches is going to be running down the steering column coming from those control switches. You'll be able to tell by wire coloring coming from the steering wheel. *Edit Additional diagrams of component locations.
