I just noticed this, and had recently had my vehicle in the dealership for a motor mount replacement recently.. Never seen this before.



--------------------------------------------------------------------------

 

Like I said in my e-mail, that sure looks like the section of the harness that goes to the automatic transmission...well if you had one. Didn't they replace your wiring harness last year, or has my mind gone completely?

If they did do the harness, its probably one from an automatic equipped "donor" HHR and the tech just snipped off the unneeded pigtail. You should tape it up with good quality electrical tape to keep it from shorting/grounding out against something, and it will also keep the inevitable corrosion from working its way back into the harness.

 

Back on 4/19/2011 they did this...."Cause: Engine harness chafing at TPS signal J7720 Bulletin 08-06-04-022B 9527 WC 2.20 : Repaired wiring to PCM Connector,, Replaced 4 terminals"

Wonder if there is some connection, or if they did change out some of the harness.

Its bad when I remember your maintenance history too Kev, I already have too much stuff in my head as it is.

 

Have you determined what the wires go to? Have any codes flashed up? Nothing major I hope. Once, my ex put her Nissan in the shop for something (I don't remember what, struts or alignment, unknown to me), when I was out of town. When I returned, we loaded up her kids to go to the Coast for vacation (my S-10 was too small). I immediately noticed the looseness in the front end, but assumed that the front was light because of the full load in the rear (I never drove it that much). Just out of town, I became concerned by the jiggle on bumps. When I inspected underneath, I found both front struts were not bolted to the unibody, the bolts were not even finger-tight. I didn't have the tools to fix it, and drove carefully to an alignment shop in town, where it was bolted down and re-aligned. My ex had driven it for 3 days without even saying a word to me about it. Needless to say, the Nissan shop knew nothing about it. To this day, I try to fully inspect my car(s) before they leave any shop, unless I can watch the procedures being done. Trust No One (-Fox Mulder).

 

If you decide not to investigate this to its proper and logical end – that being having who did this correct the problem “correctly”.

I would suggest you take the DIY fix one step further and seal the ends of each of those wires individually. In my experience just taping the end of the cut off loom can lead to corrosion problems across the ends of the conductors. Electrical tape for the most part does not keep moisture out and once moisture gets in, tape keeps the moisture in to do more damage.

I do have an Automatic and from the looks of your second picture I believe 843de’s theory is correct about how this happened.

Notice the connector with the purple and gray parts, just below the cut off loom. On my Auto the cut off loom would connect there. Also notice the wire bundle connected to that same connector is “taped” up and the workmanship does not match the rest of the wiring loom.

 

I absolutely hate letting anyone work on my cars or home. Seems like there is always something done wrong/not my way!

 

I have driven my vehicle the same way since I first had it, and I know it's limitations, nothing has changed as far as the drivability. Not since the last Throttle position sensor was changed, have I had a CEL nor has my suspension given me any problems.


I believe that this was part of warranty work, as I have not let anyone other than the dealership touch the parts under the hood..

I will be replacing the Rear Air Box Bracket again very shortly, and will at that time determine where those wires go as when I traced them this morning they seem to go under the box.

I agree, but, when the dealership will do it for no cost, and if they mess it up, it's their hynie and you can make them fix it right..

 

I just went out to look under my hood 2008 LT Auto. That is the piece of cable that goes to the throttle, instead of that new one in your pic, with the purple connector. So evidently they just replaced the entire loom. All the colors are the same, I note that all of the "new" wires are white.

 

so what you are saying is, they replaced it, and were too lazy to remove the old cluster of wires?

 

Yes. They probably would have to go track the bundle to where the next Y is, somewhere behind the motor I'm guessing back there to the next set that go to the ECM like the cam sensors temp sensor etc. I will bet that if you pull the rain cover off of the ECM (that hood thing in front of the fuse box) you will see another set of cut wires where the new wires connect to the ECM connector.
