Does anyone know about the wiring for OEM steering wheel controls? My 05 tc does not have the radio controls on the steering wheel, but you can buy tc wheels with the option on it for around $50 online. If I did that, is the wiring harness in the column already pinned for the controls or would I have to run the wires?

I would love to hear from anyone who has tried this. I looked around online but couldn't find anything.
