The invisicord is just a simple 3' wires with 2 connections, one is black and the other one is yellow. You will connect the invisicord to the back of the harness on the fog lamp. On the fog lamp there are 2 wires hooking up to a connector, you will place the invisicord wire on the back of that connector. Let me know if this info helps, feel free to hit me up, I do have plenty of pictures that help illustrate the installation.
