"Replacing a Tatty Harness with Brand New Will Solve 90% of All
Electrical Problems"
The Roadster Factory sells the best wiring harnesses. Look for correct terminals and
correct colour coding. Our harnesses are made in England and stocked in the U.S.A., so
delivery is only a few days away, even when we are out of stock. A new harness will solve
90% of all electrical problems, so it makes a very good investment when doing a
restoration...
TR250 and TR6 models are fitted with main wiring harnesses, which wire the dash
and the front of the car, and with body harnesses, which wire the rear of the car. The
two harnesses join at a terminal block in the left-hand front door post. In addition to
the main harness and the body harness, supplementary harnesses and wires were fitted
for headlamps, gearbox, and optional overdrive. Virtually all of this wiring is available
from The Roadster Factory correctly colour-coded and with correct terminal fittings...
Note that good wiring diagrams are found in the owner's handbooks, although
coverage in the owner's handbook is not as good for 1969-72 TR6. Better diagrams
and a wealth of information about the TR250, TR6 electrical system are found in Dan
Masters book, "Triumph TR250-TR6 Electrical Maintenance Handbook." This book is
