btw, the headliner in the center didn't give way very much. I took out the 2 screws from the driver side visor hinge, the screw for the visor hook, and the 2 screws in the center mini visor and also the screw from the passenger visor hook. The headliner in the vicinity of the driverside visor hinge came off fine, and I was able to tuck the wire in easily but near visor hook all the way to the center it was really tough, I had to really force the wire under the headliner in that area. Did you have any problems like that?
