TWO RELATED THREADS STARTED BY THE SAME MEMBER HAVE BEEN MERGED.

Hope this post will not offend too many analysts.

There is a large , black, plastic screw type fastener holding the cover of SMJ.
These fasteners have a tendency to brake when NOT used correctly.
I can loosen it turning clockwise , but ...

THIS WAS MY ERROR - IT LOOSENS TURNING COUNTER-CLOCKWISE.


HOW do I get it OUT to be able to remove the SMJ cover WITHOUT BREAKING THE FASTENER ?

Removing SMJ cover fastener

OK, I posted this is wrong pew .
Definitely dumb....

I need to remove SMJ cover to gain access.
It is held by one of those screw out fasteners , black about quarter size , which will break when not handled properly.

I can "unscrew it" - turning counter-clockwise but still cannot get it to let go without force.

Any "fast(ener)" reasonable hits will be appreciated.

Fellas, that would be the SUPER MULTIPLE JUNCTION. Part of the power distribution and grounding system.

I'm going to go out on a limb and say it is the one on the driver's side floor/kick plate area? I saw the picture you posted in the DUMB Question Thread and poked around the X.

This is the only thing I could find on it from another thread:
After this is removed the Black Side Kick Plate which protects some wiring has to be removed. There is a big Flathead screw that is Plastic that you have to remove. This will completely unscrew out of place. Do not pull on it or u will strip the threads. Then pull on the front part of the Kick Plate which has two Metal Connectors to release the Kick Plate. Now you have full access to everything.
Now in this thread you say clockwise, the other counter. If you did go clockwise first you may have stripped the threads already.

This may not help, but I'm one of those that will keep turning until I say F-it and then pry and pray. It's only plastic.

It might help someone else help who has some experience with that area...I saw people were confused in your thread.

Thanks,
I shall try to keep unscrewing it until it comes out.
Since I have no experience in this , I just did not want to beak it and than having a time trying to find replacement.
Of course I could always cement it back in.

Update

Update
Partial success.
The fastener in question is indeed just screwed onto small stud , not one of those twist 90 degrees and pop off.
Last advice received here was of great help. Appreciate that/

Managed to pop ONE of the cover plastic nipples which attach the cover to the body.
Will probably brake the second one off if I an not careful.

Now I need to really identify the connectors. Especially "C1" .


THE BIG problem
The mess under the cover DOES not look as SMJ pictured in manual.

Back to shop manual.




PS
May post pictures if anybody is interested.

Embarrassing update

Embarrassing update
OK
I can identify "chassis harness".
From wiring diagram , file attached ,
I can identify C5 as a connector plugged into the fuel pump / fuel level.
I identify C1 connector connecting "chassis harness" to "engine harness " via connector E41.

I can identify connector M31 connecting SMJ to instrument panel..

I cannot physically verify super multiple junction (SMJ) connectors.

There is NO reference in manual WHERE IS THIS mysterious SMJ located!
And how it looks in 2007 Xterra.



MORE UPDATE
There appears to be a wire harness on PASSENGER side also. Will take a look after lunch.



The attached shot is what I found under the cover on drivers side.

Took a look around my FSA to see what I can come up with (mine's 2014). It appears the M31 connector (at least on mine) is located on the passenger side.

Thanks
I have removed the harness connectors cover on the passenger side. It should not be that hard to identify the M31.
I am not sure if 2007 pg manual has the "M" harness picture in it.
Making progress thanks to this forum.
Appreciate all the help I am getting.

Is SMJ for Real ?

OK, consider this a bump.
I am still trying to identify SMJ on 2007 model.
I actually look into other years and it looks as SMJ was once upon a time for real and now it is not.
What I have now is exposed "connector bridges" on both driver's and passenger's side of front wheel wells.
What I was hoping for was an access to a fuel level signal.
I can still do that , but will have to first identify correct connector , they are not labelled as in wiring diagram, just some manufacturer part #.
I have been getting very positive reposes from this forum, which I appreciate , but also some trolls.
It is not my intent to repost same request, but by same token I would like to make sure the trolls knows how I feel about their "posts".
Please do not ask me to describe SMJ. I am not an educator.
If you do not know what it is - you cannot help!

You are getting "trolls" because:

1. You keep starting new threads for the same problem and
2. You refuse to just fix the fuel sending unit via dropping the tank, making this whole ordeal ridiculously complicated

# 2 is hit or miss with most people, but # 1 is a big no no for forum etiquette.
