I havent done it yet but its straight forward
first you need RJ-45 jack, you can get it from home depot
next you get a standard cat-5 cable. home depot too, or computer store
MAKE SURE ITS NOT A CROSSOVER CABLE. The wiring should be exactly the same on both sides of the connector.
here is the difference:

At home depot they also carry faceplates like an AC outlet but for the RJ-45jack. might want to get that or you can find a smooth way to put it on your box.
so anyways once you got your rj-45 jack on your project box you just connect the dimming cables correctly
Pin - Usage
1 0-10vdc V1 and V3
2 Ground
3
4
5 0-10vdc V2 and V4
6 Ground
7
8
So the + of the dimming cable for one set of lights goes to pin 1 on the RJ-45 jack. The ground goes to Pin2. Other set of lights + goes to pin5, ground to pin6.
