VR6 Intake temperature sensor / PCV widget

[Serial 0]

Hi all,

 

I wonder if anyone could confirm the colours of the wires that connect to the intake temperature sensor on a '93 VR6? I just completed a rebuild and I think I may have plugged it into the wrong place, there's two connectors that fit on the sensor, one is on the main engine loom, and the other comes out of the loom that the large fan connector wires are in.

 

Also, the small pipe that goes from the head into the rubber intake pipe just before the throttle body (PCV pipe?) has a little widget on it with what looks like a connector for a cable, but without any contacts, does anyone have any idea what this is? The Bentley says its a heater of some kind, but without contacts how can it do any heating? :scratch:

 

Just got a bit confused as during the rebuild I completely re-taped the engine loom and of course forgot to note down exactly where each connector went, d'oh!

 

Cheers :)

The small connection by the throttle body isn't supposed to have connections.

 

The inlet temp sensor I think is supposed to have the connector that is loomed with the 2 thermostat temp sensors, and the other black coolant sensor is connected to the wire that runs down the front of the engine and across by the front crossmember. It's all been mentioned on here before. Try searching for it.

So the black coolant sensor on the thermostat housing doesn't connect to the main engine loom, but to the loom with the fan cables?
