The gray wire came out of the 3 wire socket on the bow light pole base on my '95 Cajun and doesn't appear to be something I can fix without replacing the assembly. I looked online and can only find replacement units for a 2 wire application, so I assume the 3 wire versions have all migrated to the 2 wire within the boating community. Is there any special I need to do when wiring the 2 wire in place of the 3 wire version?
