Rigid D2 to OEM Fog Light Switch

Ive searched and searched and havent exactly found my answer. Im wiring a set of rigid d2 dually lights to an oem fog light switch. The oem switch has the harness and the 4 connectors that come off of it. Ive seen several threads about which wire goes where but the rigid harness has 3 wires going into the switch. But all the diagrams ive seen only show one wire going into the switch. I hooked one wire up to the blue line from the relay, i tapped into the fuse box with an add a fuse just like many other threads show, and finally the bottom wire goes to a ground. But im confused on what i do with the other wire from the oem fog light switch? Do i hook it up to the add afuse or connect it to the red wire from the relay? i got the lights powered on but could not turn them off. I hope this makes sense?

 

If anyone has wired duallys to a oem fog light switch please tell me which wires go where and what wires form the relay you run. Thank you

 

I just cut the plugs off and wired the lights right in to the wires from the switch.

 

what plugs are you referring to?
