Hi there,

I'm trying to change the oil pressure gauge and water temp gauge on my boat with a 305 and a alpha one stern leg. I was hoping it would be a straight swap over but I think the poles are arranged in an abnormal way and I can't figure out how the wiring works.

I've have been scouring the internet for about 10 hours but can't find any info about the gauges or how to wire them up?

I also would not spend the money on a pre made wire harness, these are pretty simple motors electrically and changing out individual wires is not that difficult. I use THHN wire, oil and gas resistant. I have always wondered if the ozone produced is not part of wire insulation failing.
