993 Rear Fog Lights

Warning! rear fog lights are designed only to be used during severe weather or dense fog conditions where normal visibility is greatly effected.  Because the nature of the rear fog light's brightly lit bulbs it is not recommended that they be used during normal weather conditions.  Using the rear fog lights in normal weather condition may cause road rage or may even result you in a traffic ticket.

This DIY originated from Gert in Belgium, Gert did this DIY on his 993 and kindly passed his knowledgeable experience and information to me to make this DIY possible for U.S. 993 owners who want to add this option to their 993. 

993 rear fog lights are standard equipment in Europe but was not installed in the U.S. bonded 993s.  Since our U.S. 993s are not pre wired for the rear fog light, this DIY is maybe slightly complicated.
