Your problem is almost certainly a short circuit in the steering 
column. 
Here is a copy of a standard response I wrote for this problem some 
time ago.
"Your problem is 99% sure to be down the middle of the steering 
column.  Remove the two cross head screws in the back of the steering 
wheel spokes and remove the horn the horn button assembly.  The horn 
circuit is that nylon nut screwed to the top of the steering column 
tube.  If it is not screwed on or the thread is stripped from the nylon 
then this is certainly your problem as it will flop to one side and 
short circuit.  This is because there is no insulation on the brass rod 
attached to the nylon nut.  You can fix this by either purchasing a new 
part or buying a can of Coke.  In the case of the Coke, drink the Coke 
but keep the straw and use it to insulate the brass rod.  The nylon 
guide on the bottom of the brass rod can be removed with care to 
install the straw."

Let me know if that's not the problem and I'll give some thought to 
other ways to avoid the 5 hour job of disassembling the steering column 
to get at the bottom end insulator for the brass rod.

NO, be more specific - where in the trunk?  It is almost certainly an 
add-on.  Jaguar
ground wires are ALWAYS black.

>Does anyone have a wiring diagram for this model. If so, I would

I have a not half bad one (more like 75%) from the Haynes manual - 
send me your Fax number.

>I took my first extended drive in it this weekend and it was wonderful!
Yes, they are aren't they,

>Any info on cruise control would also be appreciated. I read the

alot=
1. The Stalk is the stick poking out the side of the stering column.
2. Try Kirby's XJ-S book or maybe Jim Isabell's (I haven't been 
through it yet) XJ6 Bumper to Bumper.
