1994 Albemarle Wiring

[llewis01]

I'm looking for a electrical diagram for a 1994 volvopenta 7.4. Where can I find one? Having a guestion on why my engine has 2 temp sending unit mounted on the thermostat housing. Looks like one is above the thermostat and one below it. Is it nessassary to have them both?

Sorry, thought I had a wiring diagram for that engine, but I guess not.

I would guess the reason for the two, is one is the gauge sender and the other is an alarm switch. The switch would have a tan wire with a black stripe, while the sender would be a solid tan wire.
