mately
5" in length) protruding from engine wiring
harness along
left
rocker arm cover where har-
ness breaks out for
alternator.
On Pontiac or
Tempest
6-cylinder
models
loop
will be
located
at breakout for

that new
link
is to be soldered to.
6. Using fusible
link
4
gauges
smaller than pro-
tected circuit (approximately 10" long), solder new
link
into circuit.
CAUTION:
Use
only
resin
base
solder.
Under no
circumstances should an acid
base
solder be used
nor should link be connected in any other manner
except
by soldering.
