Remove the jack module(s) from the Decora plate by pushing up on the tab with your
thumb or blunt object. The plastic handle of 110 push tool works well for this. The jack
will pop out the back of the plate. (Figure 1)
Remove the two strain relief covers that protect the connecting block. (Figure 2)
Strip off about 1-1/2 inches of the outer jacket from the wire.
The label of the jack has a row of numbers that correspond to the pin numbers. There is
also an upper and lower row of color codes labeled A and B that correspond to the
T568A and T568B standards respectively. For USOC connections, use the color code
table to determine the wire color for each pin number. (Figure 6 and Color Code Table)
Being careful no to completely un-twist the colored pairs, separate the ends of the conductor pairs so that they can be laid into the appropriate slots of the jack’s connecting
block. (Figure 3)
On a firm surface, punch the conductors into their slots using a 110 tool. (Figure 4)
Cut off excess wire. This will not be necessary if you use a 110 punch tool with integral
cutting edge.
Replace the two protective strain relief covers.
Snap the module back into the Decora plate while pushing up on the tab. (Figure 5)
