Hello, I am restoring a 99 with all new NAV etc and interior. I am trying to find out what would be needed to add audio controls to the column. I have acquired a wheel with the controls and was wondering about the wiring harness currently in the column ie. would it have the connectors for the audio controls? I have been looking for a complete column but cant find one. Thanks. Also looking for a source for a rear seat back release cable for 60% seat side.
