View Full Version : Gauge wiring question
02-08-2014, 12:15 PM
Alright guys diving into some more projects. Some of you know I have a weird boat which is a 02 209 with a Merc 5.7. Problem is I have a few gauges that are hard wired and not part of the stock MC plug system. I am compelled to get these back to stock and have purchased a new gauge set. Not to sound too stupid but how can I fix this wiring wise?

Pictures would help but it sounds like you will either need a different harness or a sub harness

Well my problem is my basic confusion I think. The oil pressure and tach are straight wired to the gauges thus making it impossible right now to hook up the original medallion gauges. Do I need to run the wiring to the mmdc and then just plug up the old plugs to the original gauges. Any help would be greatly appreciated. Trying to get this thing on the market and want everything perfect for the future owner
