Did a search and there is VERY little information out there on the s13 OEM fog light set up. I did find where somebody stated that every s13 was already pre wired for fog lights. I pulled the one cover off that supposedly has a plug behind it for the switch. I did not see the plug. If the s13 is pre wired, where is that plug? I also looked around the front of the car and did not see any plugs that look like there for fog lights. I have the Silvia conversion and was looking to hook up the fog lights to the factory wiring.
Thanks....

 

89-90 had optional foglights, way more common in japan though.
i believe the 91-94 are prewired for daytime running lights, not foglights.
but they are kinda cool looking either way.

 

Thanks for the reply Tim. I guess I'll see if I can figure out the OEM foglight switch I have and go from there. Oh well, so much for just plug and play.......

A little more involved, but more of what I'm looking to do. Since we are on the subject of lights, maybe you can help me with this rather than me starting a new thread. In another forum, they are selling the Key ignition ring that lights up green. By chance, do you know what car they are pulling these off of?
Thanks for the help Tim........

 

im not sure, id imagine some infiniti, probably an I or a Q or something.
ill see what i can find out though.

 

Tim, thanks for taking the time to help me out. If you find out anything, please let me know. Here is the one I was looking at:
