    By coincidence, the Show Me Cables reminder to review the EZ-RJ12 plugs arrived the same day that I installed one. The "Feed Through" feature is just wonderful! I was able to: [1] be really certain that the six conductors were in the proper order, because they feed out the other end of the plug; and [2] carefully arrange the conductors to avoid the kind of unusual stresses and strains that had apparently caused the original plug's #1 and #6 conductors to short out together. The cutter on the standard crimper/cutter/stripper tool I used chopped the fed-through portion of the conductors cleanly off even with the end of the modular plug. Pulling the conductors through as well as pushing them also tended to minimize damaging stress and strain. The extra 2" or 3" conductor length allowed a definitive observation of all conductors, so that no mistake was made in mistaking one striped wire for another. The extra wire remained in place until AFTER the crimp was finished, for better certainty than with "dead end" type plugs. I LOVE the "Feed Through" feature of these plugs! :-) Also, I couldn't believe how fast the plugs arrived in the SF Bay Area from Missouri! They were in my hands just a couple of days after I ordered them! Thank you, Show Me Cables!!

    CONS: None specified
    I cant tell you how many times the wire colors get mixed up as you feed them into the standard plug. these feed thru plugs eliminate that problem altogether. its as simple as that.

Q: What is the difference between an RJ11 and an RJ12 connector?

A: Both connectors are the same size and appear the same. However, looking at the contacts an RJ11 will only have 4 contacts. An RJ12 will have 6 contacts.

Q: What are the terms 4P4C, 6P4C and 6P6C referring to?


4P4C: 4 Position 4 Conductor ( RJ22) - used for Telephone Handset cables.

6P4C: 6 Position 4 Conductor (RJ11) - used for ADSL, telephone, and modem cables.

6P6C: 6 Position 6 Conductor (RJ12) - used in System phones.

Q: How do I tell if a plug accepts flat or round cable?

A: Looking at the back of the plug where the cable would insert it will either have an oval shape or a rectangular shape. The rectangular shape accepts flat cable. The oval shape accepts round cable.

Q: How do I wire these plugs?

A: Please see the resource tab for a diagram.

Q: Which pinout should I use use to attach a connector?

A: Newer phones can use a straight or reverse pinned line cord. If you’re unsure of the age of your phone a reverse pinned cord will work with any age phone.
