Yes, but *which* relay???

[Scott Fisher <sefisher@cisco.com>]

A while back, a number of q-listers were helpful in suggesting that my
newly acquired '83 GT's unwillingness to rev past 5K or so was due to
the installation of a 4cyl fuel pump relay in place of the 5cyl unit it
should have.

Being a crafty do-it-yourself type, I looked in the wiring diagrams and
immediately concluded that I'd probably wasted thirteen bucks on the
Haynes manual I bought the weekend I took possession of the car, and
should have bought the nice leather steering wheel cover instead like I
wanted. :-)  It doesn't have diagrams for the '83, and it has no
pictures of the fuse/relay panels either (but it has *lovely* color
photos of ugly spark plugs in the inside rear cover). 

The operative word there is "panels."  The previous (well, technically
still current, as it's still technically a long-term loan) owner of the
GT in question delivered the Bentley manual, which is a little better. 
Only the relay panel in the books says, first of all, "Old relay
location shown."  O-kay.  Then I further observe that in the actual
vehicle, I've got two relay panels:

Panel 1 is just above my left knee (it's an LHD car, for UK listers). 
It appears to have only about two relays left in it.

Panel 2 is under the hood (bonnet for UK listers), on the LH side of the
car, on that flat shelf between the rubber gasket that separates the
engine bay from the -- I'm guessing it's there to keep fumes out of the
passenger vent inlet at the base of the windscreen, yes?

Anyway... neither of the relay panels in my car actually look like the
one depicted in the book, and my best guess on the car is one titled
"Fuel Injection."  (The P.O. said, "see whichever one looks newest, I
replaced it about four or five years ago and they probably gave me the
wrong one then...") 

Any clues?  I have already fabricated my little test lead -- two
spade-lug connectors on a strip of 12awg wire, ready to jumper across
the terminals that power the fuel pump.  As soon as I can figure out
which of these two terminals are correct (rather than just try
connecting terminals at random and see which fuses blow, which is of
course is what the dealer would probably do...), I can try revving the
car past 5K and see if the problem is solved.  (And yes, this IS all
because I'm too damn cheap to buy the new relay and then see which one
has the same plug pattern. :-)

So... is there someone here with an  '83 5-cylinder 4000 series that
could help give me a clue where to start?  The motor is too sweet to
keep shifting at 4500 RPM... that's for pushrod V8s! :-)
