Ben, and anyone else cares,

If I had an Urq (and I don't...) with an underdash "fusebox" before I
wasted any more energy sorting out the car I would buy a used '87 coupe
GT from my friendly used car supplier (Chris Semple).  It would be a
great source for random spares, of course, but there would be two things
I would shift over to the Ury -

one, the pretty dashboard and console (although a 4kq console fits better)


two, the fusebox.  I'd cut the UrQ where it goes and weld in the metal
from the Coupe.  Also I would swap over as much wiring for the cgt as I
could.  The connections are a lot better by 1987, some harnesses could
just go in whole (rear light, instrument cluster, power locks, power
windows, eg) and some would get spliced a bit (engine management sources
eg).

I have one of those underdash "fuseboxes" in my 82 coupe, and they are
pathetic.  I have done about 4 or 5 bypass jobs on it so far, the silly
things melt and die a slow and painful death just trying to run the car.

On my site there is a diagram of the entire internal wiring of the
underhood fusebox, with that and a Bentley or two you would have all
kinds of fun doing this job.  And then you would know the wiring in your
car intimately and it would cause no more trouble...
