I recently bought this Mercury 2001 50 hp ELPTO motor, I installed it my self, and I would like to know how many gauges I can install in my boat, like temperature, tilt and trim position, because I see a couple of wires that don't seem to go any where, like a brown and a light brown/white stripe, these go alongside with the wires that power the tilt pump, and the manual doesn't seem to explain this eather. Can someone help me. Thanks. Bill
