In my 2002 jaguar x type i have this plug that seems to go nowhere, any idea what it does?

 

Looks the same shape as this

 

Because it seems to be nearly the battery:

May this the plug for the transportation switch (I don't know the exact name for it)?
This assembly to protect the battery from draining by the car will be removed by the dealer after delivery.

@catfondler
nope this is the battery shipping plug

 

Hi Andis28,

The "Christmas tree" appendage on the plug tells you it is supposed to be anchored into a body panel or mounting bracket.
Check to the lower left side of your brake servo where there are the connectors and solenoids for your fuel Evap management that are mounted on a bracket that is attached to the firewall.
On the 2.5 and 3.0 V6 there is a bit more plumbing there than the 2.1 V6 variants, so I can't do a direct comparison for you but I happened to be looking at that area myself last week.

 

His first pic has both those plugs installed on the firewall

 

Where do you see such a pic?
On the first pic I saw a huge never used "christmas tree" mounting at the plug.

I'd searched for a "3-way" in X-Type electrical guide für 2002 and up models. Nothing found at this area in the compartment.

Perhaps a not described (?) special or omitted equipment, like alarm system?
@Andis28 Do you have a hood open switch at the LH dome?


Cheers, catfondler

 

I have what seems to be the same plug in my 2006 3.0 X type.

It's fed with two Green/Black wires ( that don't look like that in photo!) and attached by that christmas tree to the smaller of two wiring harnesses that pass over the top of the starter motor solenoid. The wires disappear into the harness nearby and are thus impossible to trace directly

 

Hi Andis 28,

How may wires go into that plug.
Can you tell us what wire colour and stripe colour each wire has please.
Hopefully we can identify this plug by wire colour coding.

 

My answer was to this comment =

The first pic has both the plugs on the firewall that have to do with the "evap" plugged in and in the bracket.

 

Hi Dell,

Thanks for the observation and correction, as I said 2.1 is quite different in this area.
I doubt I could get as cleaner picture of that area as the extra vacuum hoses on the 2.1 model deprives you of good vision and physical access.

 

So, I went and looked at my car just now. Bear in mind mine is a 2006. I found the plug and will attempt to describe where it is. As for what it controls/does/connects idk, the wiring towards the engine goes into a large wiring bundle. The wire colors on the plug are black, white, green & white/green. The connection to the left (right looking into the engine bay) runs into a plastic rectangular covering.




The covering =

The smaller round wire above the metal junction tube is the plug wire into rectangular covering


On a LHD on the left side (right side standing looking into the engine bay) just to the engine side and under the coolant tank is where it's at.

Here is a shot on the engine side of connector and wire colors



The plug wire going left (right looking into engine bay) close up (going into the rectangular covering).



Close up of the plug going left (right looking into the engine bay) with wire colors.



A closer view of where the plug is found under the coolant tank. It is "Christmas tree" anchored into something that I couldn't tell what it was as I didn't want to detach it just for curiosity.



That's where it's at, for what, idk, lol! Also realized it's time to clean my engine compartment after winter, it's filthy and usually looks like this =

My response was not directed to you, buddy. It was to the new Bavarian troll's post.

Its position would have me thinking plug JB145, but that is a 8-way black plug which has multiple functions (trans selector to operate reversing lights, PWM signal to operate front cooling fan speed and a feedback line form the fuel pump module and inhibitor switch line from clutch pedal or park neutral selector switches), like the image Dell posted.

This however appears to be a 3-way connector, which I am wondering if it is JB133 - the connection point for the Left front wheel speed sensor perhaps?
If it is it would only have two wires into it (White/Red and Brown/Red).
It is in the general area (listed as located behind left wheel arch liner), but might be/maybe worth a quick look to see if the left front speed sensor cable is present from the front Hub assembly and tracing it back up into the wheel arch.

 

Well I've solved it for mine . It's the connection for the reversing lights switch on a manual gearbox. Unused in those cars having an auto box and therefore 'parked' by plugging the christmas tree into the plastic loop attached to that harness passing over the starter solenoid.

 

Wow!

It looks like Dell even waxes his radiator support and shock towers! Now that's what I call dedication.

 

Actually I use a hack I discovered years ago. Lift hood, take a can of tire cleaner, spray EVERYTHING (cold engine). No need to concern yourself with any electrical components like alternator, etc. It won't hurt anything. Where there is extra heavy grime you can use a soft brush to loosen the debis. Let it sit 15-20 minutes then just blow it out/off with air. If you don't have a compressor, a leaf blower works really well. Wipe any areas needing attention with a soft cloth. It cleans everything and makes your rubber hoses and plastic parts look like you ArmorAll'ed them. Easy, fast, no mess.

 

@astromorg

I don't think that's it. Mine is an automatic and as you can see from position (just under the coolant tank) and the 4 wires on right (left looking under the hood) & 3 on the left (right looking under the hood) it certainly serves some electrical connection function. I tried looking at the electrical schematics to search the colors of each side but, that gives me a headache. I think I'd leave that to Thermo, he seems to thrive on minutiae :-) :-) :-)

 

Further research

Note that the OP's engine is a 2.1 liter. A significant difference with these models up until about MY2002 (ie calendar year 2001) was that they were fitted with a vacuum pump for the brake system There was control module under the battery and the pump was fitted next to the brake servo. In Sep 01, a TSB was issued instructing dealers to remove the pump if it failed and not replace it. Experience had shown it to be unnecessary. The TSB can be found here

http://www.jagrepair.com/images/TSB/...uum%20Pump.pdf

The harness between the module and the pump should have been cut off and taped up, but some, like me, would have left it entire, 'just in case'!
If Andis28 checks under the battery, he'll probably find more evidence.

 

The OP is a 3.0 according to the signature
