Help identifying engine components
 

Hi

Trying to understand the wiring on an '86 3.2 engine. There is one part of the loom that connects to the starter, the alternator and a few sensors - but I am not sure what the sensors are.

Starts with this connector:

From what I can tell so far:

Blue = Wire from alarm to alternator
Yellow = Wire from ignition (start) to starter motor
Green / White Stripe = Oil Pressure Switch to Oil Pressure Light
Red (one of them) = Alternator to "Power distribution system"


I think the extra wire you can see to the left was where someone tapped in to this to take an additional power feed

The two sensors are, i believe:

Oil Pressure Switch (wired to the oil pressure warning light with Green/White wire (bad photo I think))

Oil temperature switch (is this wired to a warning light - or does this control the cooler fan along with the switch in the cooler itself?)

Can anyone help me identify these?

I believe the green/white is the oil pressure switch which connects to a 14 pole connector then to the oil pressure gauge light.

Thanks, that was the conclusion I came too also on that one.

Just need to know if the temp switch on the other side is just a switch for the oil temp light, or it actually controls any part of the cooling system!

I truly have to admit, I don’t recognize the 8 prong plug except from an early turbo CD box
The oil temp switch is another item I don’t recognize

I don't recognize the plug, but the sensor in the top pic with the green wire is the one for the low oil pressure warning light. I don't remember what the preset is, but it will light up the warning light on the gauge if oil pressure is too low (maybe 0.5 bar?).

Assuming the bottom pick is the sensor on the breather cover, I believe that is the temp sensor to trigger the fan on the oil cooler up in the front fender.
