 splicing old and cat 5 wire
I have recently rewired my home phone lines replacing the 4 wire (black,red,green, yellow) with 4 twisted pair cat 5 wire. However, I have a water meter transmitter which sends the meter reading through the phone lines. This line has a RJ-11 plug. Since I can't rejunction the meter transmitter to a T568A plug, is the correct slicing of the two cables as follows:

4 wire (old) to cat 5 (new)
1st pair
green splices to white w/blue (tip)
red splices to blue (ring)

2nd pair
black splices to white w/orange (tip)
yellow splices to orange (ring)

Dear Art,

If you had no other choice then to splice then the color coding you listed is correct but a 2 pair rj-11 (really an rj-14) will plug into and mate with an 8 pin jack wired as T568A and mate up the same as you listed.
