William Sadlor wants to know about MG-TD wiring harness.
Lay the harness out on the ground. The long leads, to the rear
tail lights, etc, will go to your left. Grab the Big
portion and it goes along the front of the firewall. The long
portion then goes down the firewall (in front) and underneath the
car along the steel chassis (along the left hand side of the car). There are
supposed to be clips that
attach to the steel chasis to hold the harness to the chassis.
The under dash portion then goes in the inside of the car through
the large hole just beside (or underneath) the voltage regulator.
There is supposed to be a rubber grommet in this hole to prevent chafing
of the harness.
Connect up the underdash portion inside the car.
WARNING: Take the battery OUT OF THE CAR. PLACE THE BATTERY IN
ANOTHER COUNTY IF POSSIBLE. Connect up the harness by using a
4-6 volt battery charger in place of your car battery. Check out
each item as you wire it up. ie. the parking lamps, headlights,
fuel pump.
It there is a short, the charger will peg to full charge, but there is not
enough current to fry the harness. If there is no connection, the
meter will stay at zero. If the item works you can tell. Note:
the headlamps will draw enough current to peg the meter, just
check to see that the lamps are on. It is simple if you to
it logically and take your time.
It only takes a second to completely fry your new harness if you do
something wrong and test it using the car battery. Use the battery
charger for all testing until you are shure. Suggestion, you
probably need to make separate leads for the parking
lamps as the connectors for them are inside the engine compartment.
And these leads are not usually supplied with the harness.
I made a separate ground connection for these and put it all together
with heat shrink. The original lamps are grounded through the
bolt that holds the lamp to the fender. A separate ground wire
is more secure. If you have turn signals, be sure to check them out
this way too.
If you send me your USNAIL address I can xerox parts of the shop manual
so you can see the location. Do you have the wiring diagram?
Remember (it is not clear from the diagram) the wiper motor switches
on the GROUND side. NOT the hot side as you might think.
