The Stovebolt Site Forums The Shop Area Interiors Cab marker lights

What's the easiest (or least difficult) way to get the wire up to the cab marker lights? Times before,on different kinds of trucks,I've taken it up the windshield post,but it was a real hassle fishing it through,and I've run it up the back wall of the cab,but it got lost somewhere across the headliner for a week. What works best for you guys? I'll be doing this on my '57 F350,my '54 350,and my '74 one ton. If it takes pulling the headliner,how is that done?

Tie a small piece of cotton ball or rag on the end of a string.Use a shop vac to suck the cotton ball and string through.Another way is to use twisted wire and use it to fish the wire through .About tree feet of Bailing wire or aircraft safety wire works best for me.Both ways take patience,good luck.

An old speedometer cable works great! You can twist them and push on them at the same time, and they just seem to find the right path pretty easily. Works for me almost every time.
