About 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.

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.

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
I feel like it will simplify wire installation. There's a bunch of tight spaces behind the dashboard that I wouldn't be able to properly fish a wire through. I also plan to use this also the floorboards to run speaker wire. Unlikely that it will work for this purpose, but if it works on wire behind the dashboard, I'd be happy. [ Chris  Jul 08, 2019 ]

Seemed like a useful tool during this installation. [ James  Jun 18, 2019 ]

Not a professional installer, however have put quite a few different applications into quite a few different vehicles. For my big fat hands, hands down the most difficult issue is feeding wires thru the fire wall. This product seems to help solve that issue. If it performs as advertised should be worth its weight in gold. [ Jesse  Dec 29, 2018 ]

I was introduced to this product by Crutchfield adviser Gus. Based based on the project I am doing this tool looks great and easy to use. I usually just use a wire hanger but I like that this is plastic, flat and don't have to worry that I will scratch anything. [ Jose  May 02, 2018 ]

I got this after one of my friends ran a wire through his door boot and blew out his master switch. We had to take the door off and spent hours cutting and soldering. I have used a coat hanger many times but after seeing that I am going to stick safe tools. [ Brian  Feb 21, 2018 ]
A
Because fishing wires under the dash and through the fire wall is a pain in the butt! I read one persons statement that I should straighten this out as soon as I get it, will do that and hopefully it cuts down on the frustration of the installation process. [ Richard  Jan 28, 2018 ]

A
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).
