I just got a 2003 steering wheel and airbag out of a wreck for $200. That guy was asking $100 for the connectors. I thought that was way too expensive. I have asked a couple of people on eBay to sell me the connectors and I will wait to see if they accept my offers. They were selling the switches along with the connectors and bit of the wiring.
I just finished installing some of the dash trims and its starting to take shape. The switch for the convertible top did not require extension, so i was able to connect it as it. The three remaining slots are for the lock switch, rear defroster and a 12V USB output.
I am going to replace the kenwood stereo with a nice system.
