Anyone know what this unconnected 3 pin connector is and what it maybe should be connected to on my 1985 S2 4.7 auto?



It would be great if I could find an under bonnet identifier for the S2 like there is for the S4, if anyone knows of one that would be really helpful.

As always, thank you all!

It's a test port plug-in. I forget for what, but it is not used and apparently never really was. The plug wire goes into the rear of the engine, just below the TPS sensor. You can pull and toss or just ignore it.

As Ed said, this is an unused system,
its for a secondary crank position sensor used at the dealer.
I usually remove the sensor,
then JB weld a quarter over the hole.

Woops, yes, CPS not TPS.
