I am going to work on my sagging head liner. does anyone know where the wires run? is it right down the center or off to one side. Thanks

 

If you mean the wires for the overhead lights, the wires on my 97 clip to a brace that also holds the lamp housing. The brace runs laterally across the cab right behind the drivers head.
If you have a forward overhead console, the wires for that are clipped to a lateral brace between the A pillars.
The wires run from the lamp / console to the drivers side and then runs forward to and down drivers side A pillar.

 

Thanks for the information.
