2001 996 fuel injection wiring harness sensor plug help

[EddieLove]

hello,
so my problem is this... I have a 2001 996 that suffered D chucking, and it blew a hole in the block. I had no choice but to purchase a replacement motor, I bought a used motor from a Porsche dismantler but when it was delivered to my home I realized it was from an earlier version without the drive by wire throttle :-( because of this I removed the existing wiring harness from my dchunk motor and all the sensors from my motor and replaced all the parts on the new motor. Now my problem is I have an extra clip on the wiring harness that I can't for the life of me figure out where it goes. The clip looks identical to a fuel injector clips. it is on the 456 cylinder side of the motor(near vacuum switches and splits off the harness where the wires come out from under the intake manifold to wrap down the side for injectors and coils.. I have of course plugged in the 3 fuel injectors and the two vacuum switches, there is also an identical switch plugged in near the throttle body on a black tube but I still have 1 remaining that I cannot figure out where it goes I have spent 12 hours taking everything apart and putting everything back together but cannot for the life of me find where it is can go! I can anyone help please??? I feel really foolish for being unable to solve this riddle. again the plug is identical to a fuel injector clip and the wire colors are red with blue stripe and red with a violet stripe.

Hi You should include a photo if the clip or plug that you talk about. That would be some help. Some one might recognize it. JW

Could be the for the engine compartment fan sensor that sits on the intake manifold between 4 and 5.

Get a pic.

What color wires are in the connector? A quick look at the schematics will eliminate speculation....

hey i am having this same problem...did you ever find out what it was?

Hi, Are you sure on the wire colors? As soon as the snow goes away I will check my 911. I noticed a test plug around that area however I didn't remember the colors. I think a similar plug like the one the fuel injector also would fit on the tank venting valve or the intake pipe change over switch.

i looked it up on a wire diagram and it said something on the lines of a water shut off valve? any idea what that would be?

[jwgn777]

On your wiring diagram did it say cooling water stop valve and did the circuit lead to the Tiptronic controller and mark as ATF valve? If so that is for you trans cooler. If you vehicle is a manual trans perhaps it is just an unused plug now. JW
