Ok, so we are working with a: 2000 GLX with the 1.8T and a 5 speed. Please update your info; that way, we can know what your car is (update your profile info; it will show up under the right side after join date and location: put year, model, engine, and trans). Thanks!
It kinda looks like the same area; for the MAF connector, is there a maf plug in your car now? Three wires; doesn't seem like enough though.
I still haven't been able to find where the heck these goto at all. None of the wiring diagrams I have show any connector with those 3 wires. Just seems weird to be something factory like that wrapped up in tape...
Can you take a picture and describe, more clearly; where this sub section of the wiring loom; is coming out of the main wiring loom you are referring to? If I can pinpoint; more clearly, what you are referring to, I can look at my car and try to figure it out. I was thinking; some sort of sensor plug; with three terminals. My car is a 2002 AWP 1.8T with a 02M six speed but I would assume it is similar to your 2000 5 speed, 02J...1.8T. On my car; I haven't found any factory "unused/taped"; subsections of the wiring loom, that I have seen so far. If there was such a thing; I think it would be odd, for the terminals to just be out there, easily ground out on something. :screwy:
Strange; I am not seeing anything either! If you can get a photo; at some point, where it connects to the harness, let me know! On that side fo the engine; I am seeing these sensors/plugs: coolant temp sensor, brake master cylinder pressure sensor, sensor the connects to the side of the trans (reverse light switch), oil pressure sensor/sending unit, speed sensor, etc.
Another thing; that just came to mind; the 1.8T is known for misfires and many times, it is related to coil pack connectors and cracked wiring harnesses. VW sells a overlay replacement harness; that is somewhat universal and all the wiring connections may not be used. I wonder; if this could be the case with your wiring harness and it was replaced?
Here is an example of a overlay raplacement the harness; for the 1.8T. Note: you might check the diy's listed below and see if some connections are unused on some applications/cars.
Hmmm, this is odd.
I'm gonna take a peek under my beetle's hood and look at the leftover wires from my 5-speed swap. Maybe it's an automatic trans related wire/connector.
When doing Cup's first timing belt service, I noticed a little connector wrapped in a little heat shield bag. I never knew what the purpose of that connector was, until I swapped out my auto trans. for a 5-speed. The connector was for the speed sensor (speedometer) for the manual transmission.
I'm saying all.of this, wondering if VW, by design, made one universal wiring harness for both auto and manual trans.? Maybe this is the case of the mystery wire. So, I'll check my engine compartment and see if your mystery wires are auto. Related.
Funny, how the wires are exposed though. Odd.
EDIT: if there's a connector at the end of the wire, a view of that connector would be a help too.
