I made these diagrams to line up with the fuse placements. Also fixed the switched "not used" and "dimmer" slots (least in a 4.2 car). I Keep each corresponding diagram under the fascia door for each fuse box.
This makes it SO much easier to check for a bad fuse, when you're completely fed up and "Oh man, NOW what!"

 

It's the little things in life that drive us nuts!
Just printed this out for my cat. Thanks for doing this.

 

Dude seriously. I blew a fuse, installing Bluetooth, and everything was opened up, I'm trying to figure out the crazy wiring...and last I needed was to decipher that crazy fuse guide, that didn't line up AT ALL with the boxes. You know, like EVERY other cars actually DOES.

 

Julian - Thanks very much!
Can you recommend a good XK8 mechanic in LA? (For issues such as lean condition, restricted performance, replacing tensioners, ABS, airbags, ...)

 

Yep, I use Just Jaguar in Sherman Oaks 818 995 0416.
The guys and girls there really know their stuff, and they'll talk to you like you do as well. No other cars are there, no BMW, Mercedes, just jags. You could name drop me, if you like.
They are not cheap, as they only use OEM or equivalent parts. And they would rather replace bits, than try rigging old bits. And they stand behind all their work, do a few return freebies, if strange noises happen after work done. We all know that bits break, when working on these things now.
They will also do a beginning inspection, get you as close to 100% as possible, and keep a record of you car.


Now if you need parts and bits that are used, there is Galaxy Auto for Jaguar (818) 899-9494 Avo is the owner. They will do mech stuff too, and the guy seems to know his stuff. They did mine catalytic replacements, where Just Jaguar wont do those. But they are better for stuff that can be repaired with broken cars from their lot.
