Is there a "complete" set of wiring diagrams for the XK series?
I have a download titled XK range, 2003 model year Electrical guide but it seems very incomplete.
For example, there are 13 pins in a 20 pin connector that goes to the three gauges in the center using FC79 connector but the only place I have found it is for the pins that pertain to the lights. I have looked for the other pins in this connector but have not found them.
Also, many pages of this PDF show wires going somewhere else but no indication of where and they dont seem to be on the next page which one would expect.
Any and all assistance id appreciated.
Thanks

 

Well, I pretty sure that is complete. Start by reading from the top, (not just jump to the schematic) and you will find a good deal of information on how you navigate through the electrics.
At the bottom of every diagram you will find symbols, circles, rectangles and triangles with numbers in them, referring to where the "lost" wiring comes from or goes to. The symbols and numbers tells you if its constant power, ignition power, ignition ground, canbus etc.
As for the FC79 are you sure that more of the pins actually are used?
If you look at the minor istrument pack in the instrumentation diagram you will see both warning lights and gauges

 

If you have a sat nav car, the pins for the minor gauges aren't installed at the factory.

Is that what you are looking for?

 

No sat nav. Did not know that was an option.
There are 13 pins on the connector to the 3 middle gauges. It is a 20 pin connector.
I have determined what each of the 13 pins is used for by tracing back to the two plugs on the main instrument cluster, not by anything I can find on the wiring diagrams.

 

I wish it was that easy. There are many times that the wires just go off of the page with no reference to where to find the other end. See the attached photo as an example. It is almost like there are missing pages or that the pages were somehow cut off. Is that possible?

 

Update
I tried a different download of the wiring diagrams and found that what I was using was indeed incomplete.
Not sure how it got corrupted but at least now I see that it was the PDF I was using and not me losing my mind.
Still nee to figure out why my instrument lights go out when the headlight switch is turned on. It is giving me voltage on the correct pin when i turn the dimmer override on, Just no lights
Thanks

 

It's all in the 2003 electrical guide.

 

@baxtor I agree if you are working with an uncorrupted PDF of the diagrams. See post #6

 

Giving you voltage? You should have ground! Both ignition switch and light switch are ground feed on the XK8.
Turning the lights on you should have ground from the lighting switch to the dimmer override switch (Red/white wire on my 2000 xkr) with override switch on you should have ground to major instrument pack on the red/green wire.
Look at "Dimmer controlled lighting" in your electric diagram
