Overview

Our take on the Pro.Fit Wire Worm

Pro.Fit's "Wire Worm" tool helps you route your wires during installation. Just tape your wire to it, then fish it under your dash or carpeting, or push it through holes or behind panels in order to pull the wire through to the desired destination. The 48-inch, rigid nylon Wire Worm stays straight, yet it's flexible enough to handle corners. And it won't scratch your vehicle's interior or existing wiring.

Warranty: lifetime.

Uncoil this device and stretch it out as soon as you receive it. If you do this, it will work just fine. Worked great for fishing the video cable from the backup camera to the head unit.

Features

Overview: The ProFit DM-45-33 Wire Worm is a specialized tool to assist you in routing wires under the dash cavity, under carpeting, above headliners or through your vehicle's firewall. It is 0.385" wide x 47.875" long and made of nylon that is rigid enough to follow a line, yet flexible enough to turn corners without collapsing. It will not scratch or cut your vehicle's interior or wiring and will not harm any components that it comes in contact with. You can either thread your wires through the 0.125" x 0.25" hole at either end of Wire Worm or use electrical tape to secure your wires to the end of the Wire Worm.

To make it easier to get speaker wires under the carpet to rear of truck. [ Terrance  Dec 11, 2016 ]
I have tried fishing speaker wire for vehicle installs with a standard 50-foot fish tape and it was way too stiff and the tip got caught repeatedly on the pull back. I am hoping this will be much better for pulling speaker wires and RCA cables through the flexible rubber wire passages from the cab of the truck into the doors of the truck and if needed, behind the dash of the vehicle as well. [ Howard  Dec 05, 2016 ]
This seemed like a better choice than the bent wire coat hanger that I might have used. This shouldn't scratch up the car. [ John W.  Oct 15, 2016 ]

Helps fishing vehicle wiring. [ THOMAS  May 22, 2016 ]
I worked as a bench technician at a customer stereo shop while in college, and we used something similar for fishing cables through walls. This tools is shorter, as it's intended more for mobile audio use, but it's still a great tool to have. It'll come in very handy when I have to fish the new speaker wire through the roll and sound bars in my Jeep (I was going to just use a straightened coat hanger, but this is more flexible, and should work fine). [ CHARLES E  May 11, 2016 ]
