RE: Using RJ45 crimp tool

The order previously stated below does a good job for reducing noise if
you use this cable for Telephone or Ethernet. With that pin-out the T/R
pin are twisted together and the A1/A2 pins are twisted together so you
get a better Common Mode Noise Rejection which makes it suitable for
Telco or Network (<= 100Mb/s).

But I do believe the TIA568A (see 568B for cross over) standard colors
are:
1 White Green (Ether TX+ 1)
2 Green (Ether TX- 2)
3 White Orange (RX+ 3 / Telco A1)
4 Blue  (Telco TIP)
5 White Blue (Telco Ring)
6 Orange (Ether- 6 / Telco A2)
7 White Borwn
8 Borwn
