About a week ago, my Uniden Radar detector ( ) power cord which uses a RJ11 connector broke off. I used Loctite FUN-TAK Mounting Putty ( ) for temporary fixes for my plastic parts such as to hold connectors together, such as for my RJ11 connector with a missing tab. It held the connector in place for about 3 days without issue and was easy to remove.

Its time to remove the temporary fix and replace the broken RJ11 telephone connector ( ) for my radar detector.
My trusty crimp tool ( ) does both RJ45 / RJ11 connectors and i have been using it to fix network plugs as well.

For RJ11 jacks have 4 pin connectors and is pretty simple to figure out.
Just write down the order of the color cable or take a photo for reference.
I use the crimper tools sharp cutters to score the housing and cut the ends off for a straight even cut of the wires. It comes out aligned and ready. Just pull off the scored cable housing and sort the colored wires.

Slide the wires into the new connector plug and crimp using the crimping tool to seat all the wires. Overall it only takes about 20-30 seconds. The most important part is checking the wire color order. Lastly check the cable to make sure it works .Now my Uniden Radar detector ( ) and it powers up!

Overall its good to know how to fix and replace broken RJ11 and RJ45 connectors for many applications for the home or car repair as many cables now use for data and power connections.
