That A-pillar wire was probably for visor light, dome light, something up there. I would just go through all the wires under the steering column again to make sure they are all connected. Make sure the negative wires are all connected too.

There is a joint connector on the driver side up behind the dash. Joint Connector 7 is the junction for all the CCD networking on the truck so if the connector is loose or not socketed good the NO BUS will be displayed...
