[Mk2] [NA] Small plug near throttle body... where it go?

[robo]

Hi Guys

Sorry, I can't spot where this plug goes back on a NA auto? Its near the distributor and attached to the same cable that plugs into the base of the throttle body. Any pointers appreciated



Cheers

Colour of wire?

That was fast - thanks!

Single yellow with green stripe... or may be blue because of the dirt?

Yellow/Blue = oil pressure switch. On end of head.
Yellow/Green = water temp. sender. On coolant manifold.

That plug has beaten me! Normally the wiring is idiot proof but I've tried to look all over and even use camera to access awkward bits and nothing is obvious. Would I be looking at a hard mounted socket or one hanging on a wire? Couldn't find or feel anything useful on the coolant manifold.

As the engine is a 93 and the car a 92 I was beginning to wonder if it was ever connected? Based on it being yellow with green strip and an oil sender will there be an issue running with the sender disconnected? As ideally I need it running later today.

Another photo of the bundle it is attached to ... sender circled

Doh muppet of the day... found out in my haste I'd added a hose to the sensor housing

So here's the plug on the sensor in the right place on the coolant manifold:



I had been looking around the distributor for a possible oil leak reasoned it may have just been the rocker cover so that's all been retightened. We'll see
