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....
