First ever post...I recently purchased a 1993 Four Winns Horizon 190 with a OMC 5.0L motor. Did some work to the water pump and removed some wiring to make things easier. (I did say Easier) . The large round plug that connects the instrument panel has a small rubber 3 wire connector coming out of it and I can not see where to plug it back in. There is a Green/white, blue/white and red/purple wire going to this rubber connector. Hope that helps.... I can post pictures if it helps...
