Minimum set of fuses, relays to run the car?

Car details? - we'll need the lot.
ECU is an older term which confusing has E=Electronic or E=Engine. PCM is standard, though Jaguar tend to use ECM.
You'll need to power a LOT of things or get some scary codes / immobilised / etc.
If you have a dealer-type tool such as Mongoose JLR you'll have more chance of at least clearing them.
If you upset it and get into anti-theft you're going to need that dealer tool or a tow
Is it a short or just a drain? If the latter, I'd leave everything powered and start by checking voltage across each fuse, engine running, engine off (key out), and again after 40 mins. Expect mV but only 0 if really isn't powered. By all means remove a few non-essential items but there aren't as many as people tend to guess.
Other things to check: any aftermarket items, water in boot (trunk), water dripping onto PCM (it's behind glove box).

Hello,
The car is a 2000 s-type V8, VIN SAJDA01D9YGL39635, 47K miles on it.
I am chasing a problem that keeps blowing fuses 4 and 20 in the passenger compartment fuse box.
Thanks again.

Thank you for replying. I have the wiring diagram for model year 2003, I hope it is similar to 2000.
I will update the trouble shooting effort in the below thread, since the title is more appropriate.

There is a lot of difference between the 2000 and the 2003 S Type. You should be able to get the early electrical information on this site?
