the cover that they're talking about removing is the plastic panel directly below the steering column... which will also require removal of the "carpeted" cover that goes under the rest of the dash.. should come out pretty easily. as for the passenger side, the wire your looking for is indeed yellow, but it's likely got a few conductors inside that yellow jacket, so it wont be skinny. if you get your hands on the new harness, you'll be able to see what the connector looks like. the connector is also yellow.
