I'm in the process of installing an aux tank in my 2005 Seafarer 228 and spend an hour tracing the sender wires back to the dash. I'm curious about this pink wire. At first I though it was one of the 2 sender wire but after doing a continuity check this wire is not for any of the 2 senders. The pink and pink/white sender units run through the connector I identified with my finger and continue up into the dash. Pink goes to Yamaha gauge and pink/white is behind switch panel - spaded but not connected to anything yet. The wire I'm curious about is further down the main harness (blue arrow).

Wire goes to a spade terminal and then continues to another spade terminal (long since corroded away but circled in blue. This wire was tucked inside the factory wire loom. Can anyone shed some light on what this pink wire is for? I see pink and I think fuel. I also admit this wire could have been red and faded to pink over time. Hard to tell.

Any insight is appreciated.
