Electrical Problem please

[mr steve wayne]

I am getting closer to starting my engine on my restoration project my 1984 Sea Ray 5.6 Seville Cuddy 150 ELPO with a Mercruiser 260 engine. I will be excited to hear this motor later today for the first time. I am having trouble finding my correct wiring diagram after all the ones I have seen and downloaded. With that said, I was hoping someone could tell me where this wire is to be hooked up to. It was unhooked when I purchased the boat. It appears to be a Tan or White wire with a blue stripe but none of the wiring code color shows this color used by Mercruiser. It has a round connector attached to it but I do not see anywhere it goes.

Thank You for your advice

Mr. Steve Wayne

Mercruiser manual 15 page 393 shows the tan / blue goes to monitor system for water temp, oil pressure and trans temp. Being located where it is, I suspect oil pressure switch (not sender).

That manual is for later 80's, but should be close in your case.

Thank You, I will keep looking around that area for one of those items to attach it to. The problem is I see nothing, water and oil pressure is already in use. Maybe if I can find trans temp to plug into.
I am still looking...
