Our take on the Pro.Fit Wire Worm

by Buck Pomerantz
Pro.Fit International

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.

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.

Pro fit wire worm

Written By Doughboy1338, Troy, MI on Friday, August 16, 2013
Crutchfield Customer Review (What's this?)
 
Not really necessary. A coat hanger or old piece of wire could do the same thing. I had to cut it down some. I found it to be a little too wide.
Pros:
None
Cons:
A little too wide.

Pricey but good.

Written By Pass2srf, Honolulu on Monday, August 12, 2013
Crutchfield Customer Review (What's this?)
 
The Wire Worm tool worked perfectly. I would suggest you open the package, and let it "straighten out" overnight from the coiled up shape it is shipped in. But the tool did the trick. threaded my microphone wire through the dashboard easily. Only two stars because I paid this much for a $1 piece of plastic.
Pros:
Works as advertised.
Cons:
Expensive for what it is.

Unfortunately Did Not Help

Written By Rhfactor, Tucson, Az. on Wednesday, May 01, 2013
Crutchfield Customer Review (What's this?)
 
Unfortunately the Worm did not help in the application I was trying to use it for (not flexible enough). It may be helpful in the future for install under carpeting, etc. I was trying to run speaker wire from top dash area to side to get to door speakers, it was such a cramped area the Worm just wouldn't work. Had to get someone will very small hands to do the job.
Pros:
Hopefully will be helpful for future installs.
Cons:
Just about everything in the application I was looking for.

Wire Hanger Does The Same Thing - Cheaper

Written By Anonymous, Sumter, SC on Saturday, May 26, 2012
 
This does nothing a cheap wire hanger wont do. I found it less sturdy, too, for those long reach scenarios that require a bit of pressing to push through. All in all, I got back out my metal hanger, unwound it, folded the end to make a U shape about 6 inches long, put my wires inside the U, taped it securely at top and end, then pushed on.
Pros:
None
Cons:
Didnt handle the job

Cheap and great

Crutchfield Customer Review (What's this?)
 
I bought this because I wasn't sure if I was in need of it or not and thought it couldn't hurt as it wasn't very expensive. When I got it and opened it, I was really kind of leary and I was ready to just write it off but man, did this help in my project and it is one sturdy little tool. I was able to pull cables through my entire truck with no problems and this tool worked everywhere.
Pros:
sturdy, small and will fit anywhere

Pro.Fit Wire Worm

Written By Chris, St. Louis, MO on Tuesday, September 22, 2009
Crutchfield Customer Review (What's this?)
 
This Wire Worm tool is FANTASTIC. Yes, you could use a wire hanger or a giant zip-tie, but the wire worm is very long, completely smooth, and will not scratch the interior or snag while running it under carpet/door sills/seats, etc.

The only complaints I have are the price (less than $10 would have been great) and the fact that the tool needs to be straightened for a few hours (or overnight) before use.

I just stretched it out straight and put a heavy box on it overnight. The next morning, it was perfectly flat.

This is a MUST HAVE for anybody installing an audio system in their car. It can find its way through anything, then you just tape whatever you need to pull through and pull it through!!! That simple...this tool made my installation SO much easier. Without it, I would have given up and went to an audio shop. Great Product!!!

Best car audio installation tool you could ever purchase!!!

Written By Tony, San Diego, CA on Tuesday, March 03, 2009
Crutchfield Customer Review (What's this?)
 
I agree with Ronald from Chicago, as well as everyone else that rated this product so high. This is by far the best car audio installation tool you could ever buy! I also purchased a couple of the door and panel trim removal tools, which don't get me wrong, came in very handy. However, this tiny (but very sturdy) tool saved me countless installation hours, kept me from breaking door and floor trim, and kept me from ripping up any of my interior carpet. This tool makes installation and routing of cables very, very easy and simplistic. Believe me and all the others that rated this product....This will be the best purchase you could ever make in regards to audio installation products. It made my installation experience so much easier and enjoyable!!!

Saves Tons of Time and Frustration - Great Tool

Written By Ronald, Chicago, IL on Thursday, November 06, 2008
Crutchfield Customer Review (What's this?)
 
This is the best car audio installation tool that I have ever purchased.
Incredibly simple, it's just a thin (but sturdy) curved piece of plastic. Don't
let it's simplicity fool you, however, it makes routing power cables,
interconnects and speaker wires so much easier. I can't tell you how much
time, frustration, busted knuckles and profanity this tool has helped me
save. It's probably the best money I've ever spent on car audio tools or
accessories. You'll have your new system up and running so much faster,
as well as being in a much happier mood, if you use this inexpensive tool to
complete your install.

This is one of the best tools I have purchased for car audio installation. It
made routing my speaker wires through the stock door jam a piece of
cake. It also came in really handy for routing wire under the carpet. I wish
I had bought one of these years ago. A must have for anyone who installs
car audio.
