3 - OrWh - Data1 True
4 - Gn - Data2 Complement
5 - GnWh - Data2 True

The 8P8C is pinned per T568B, standard for Ethernet wiring.

The Blue pair is intentionally avoided, as it would carry DC if a DMX 8P8C were inadvertently plugged into some network or telephone equipment.
And, on the RJ-45 side of things:

Pin.. Category Wire Color ..function
1 ....White/orange .........Data 1+ ...Primary data link
2 ....Orange .................Data 1-
3 ....White/green ..........Data 2+ ...Optional secondary link
4 ....Green ...................Data 2-
5 ....Blue .....................no connection
6 ....White/blue ............no connection
7 ....White/brown .........common for Data 1
8 ....Brown ..................common for Data 2

Just don't use the pairs assigned to 4&5.

Most lights don't use pins 4&5.
