i want to mount a gps on my head liner. in order to do so and run the power i will need to lower the head liner....does any one know how to do it with out ruining it?

 

Well I was running some power wire for a dome light the other night, and I had to take down the A-pillar plastic and the sun visors to get it to move. There was also an adhesive or tape holding it up too. Not sure about the rear as much, but getting it down shouldn't be too hard. I then used a neat tool made for running wire. You can get it at home depot and it comes in 2 varieties. One is called "fish stix" and it's basically like a green fishing pole. I bought the other kind which was a 25 foot wire on a reel, sort of like a tape measure, but super skinny and still flexible. Best 15 dollar tool I bought in a while. I used that to run all my wire (also my home theater speaker wire in the house too)

When I had my last truck in for hail damage, they took down my headliner and put a pretty decent crease in it. No way to get it out either. So make sure you pull it down from left to right, not front to back, because that's how the crease formed. But the above method should let you get in there enough to run some wire.

Luckily I have a new truck now, and a garage so hopefully no more hail damage ever.

 

Since the headliner is molded and not fastened in the middle, you can usually just do as suggested and take some of the mounting stuff off. After you pull off the A-pillar, there's some clips on the sides, take off the dome light if you have an extended cab, and you should be good to go. I've fished wires through with coat hangers without doing any more than that.

With my first Ranger, I took the headliner out to mount something (antenna actuallly) on the roof. Once I saw how it was constructed I decided to not do that again since it wouldn't be necessary for most things (which led me to put my overhead console in without dropping it either). That Ranger was not an extened cab unit. Super cabs are even easier, I think.

 

I ran wires for my dome light and CHMSL through the headliner.
It is of a molded design and there are nice channels to run wires through.
I used a piece of flexible steel (real strong wire) from some old boat controls.
Remove the 'A' pilliar and side trim and you can access pretty much the whole headliner.
Good luck, and take your time.

 

thank you all for the info....now i just need the time and tools to put it into action
