HD: Easy-to-use Wiring Diagrams now available for vintage sports car & motorcycle enthusiasts.
The Blackstone Valley, RI - Baby-boomer Doug Jacobs works tirelessly to help his fellow car and
motorcycle enthusiasts. The problem, as he sees it, is that when a classic car or motorcycle
experiences an electrical problem, the wiring diagrams they are forced to turn to can be more
work than the wiring. These diagrams appear to be made for people who have never heard an
optometrist say "reading glasses."
The 11” x 17” Color Wiring Diagrams from Prospero's Garage were specifically created for car
and motorcycle enthusiasts who, because they've crossed the four decade mark, can't read
tiny factory wiring diagrams. The type is small and the factory or other after-market diagrams
are rendered in black and white, while the car’s wiring loom exists in Technicolor.
"I'll be the first to tell you, it wasn’t that big a problem 25 years ago when I got in this business," says
Doug Jacobs, proprietor of Prospero's Garage and once factory trained BMW motorcycle mechanic.
"It's not that the factory wiring diagrams, or diagrams from aftermarket repair manuals have gotten
worse...it's just guys in their 40s and older can't read these things."
Doubling the size of a diagram is great for older guys, but even more useful to the classic car or
motorcycle enthusiast of any age are three other features of the wiring diagrams from Prospero's
Garage – Color, Legends and Lamination.
"Color. That's really one of the hardest things for the shade tree mechanic. All those black wires
run together into a mess of electrical spaghetti. The factory manual will say a wire is supposed to
be 'N/LGN’*, but what does that mean to the typical guy who does this for fun? So I always use
the same colors on the wiring diagram that you see on the wiring loom. It doesn't require
translation." *(brown wire with a light green tracer).
“Legends – or Lack of Legends. Every component on our diagrams are labeled right there on
the page. Anyone whose done any electrical de-bugging will tell you – tracing your way through
the wires, only to have to turn back four pages to find out what component numbered “142”
actually is – well, it’s infuriating. You’ve lost your place and now you have to hunt back through
the mess to find it again.”
“Lamination. Big problem – if you’re working on your car or bike, your hands are probably dirty.
If you’re using your original copy, you can bet it’ll be useless after one or two sessions. Other guys
make 20 copies of the black and white version so they can throw the dirty copy away. Ours are
laminated and are, essentially, permanent. Just don’t wrap it around a hot header pipe.”
Sales have been brisk at British car shows, motorcycle rallies, through enthusiast groups on the
Internet, and through online sales channels such as E-bay.
The wiring diagrams from Prospero's Garage first started out as something to help out Mr. Jacob's
friends. "A lot of guys I knew had recently acquired BMW Slash 5 motorcycles. A lot of them
needed help re-wiring. So I obtained some factory diagrams, and reworked them so they could
be usable." Before long, he began supplying them to other BMW motorcycle enthusiasts, and
various BMW car club members.
Once the popularity of their diagrams spread, Prospero's Garage started offering color-coded
wiring diagrams for many classic Swedish, British, German, Italian and Japanese cars, BMW and
Harley Davidson motorcycles. They are working constantly to expand the line – often the biggest
constraint relates to sourcing the factory diagrams they use for source material. New offerings
for 1960’s and 70’s American muscle cars are in the works, as well as an ever expanding line of
European & Asian classic sports cars – and even classic Toyota Land Cruisers and Ford Broncos!
