Oil sender type to gauge PN?

[5:00]

I've done some searching but not sure about the sender. My boat is 8 hours away. I have a 2007 XLV, 325. Trying to find the part number for the oil sender to the gauge. If not does anyone know if it is a 1 or 3 wire system?
Thanks!

Just replying to my own question. I was reunited with my boat and found it was a single wire. Since half of my gauges were falling apart, again, I went with a multi-function gauge. Fuel, voltage, temp and oil pressure. I moved some gauges around while I was at it for a better layout. The new gauge worked pretty well but still need the sender. Got it at Bakes part# 645002. We'll see how it goes next week.
