Primary igntion harness

It's been widely publicised in the past that the correct replacement
primary ignition harness for the CV is the Borg Warner G202 or
Standard Ignition RC-6. The primary application for this part is the
early eighties Chevette 1.6, but no one to my knowledge has ever found
a Delco part number and published it.

Hacking my way around the new ACDelco online parts catalog I was able
to determine that they do offer this part - D219. If you look up the
Chevette application it will come up, and if you click on the part
number you get the photo. It also crosses from the above B-W and
Standard part numbers using the online cross reference.

This IS the correct primary harness for the CV, but no one lists it in
their catalogs. BTW as with B-W and Standard the part is named
"capacitor" and it includes both the RFI capacitor and the complete
harness. It should really be called "harness" or "harness w/
capcacitor", but the automotive parts nomenclature game can take some
tricky turns.

It's common for the wires of this harness to break where they exit the
distributor, which can either cause intermittent misfire or a complete
shutdown of the HEI. Keeping a spare on hand and frequent inspections
is a good idea.

You're correct, "It's common for the wires of this harness to break
where they exit the distributor, which can either cause intermittent
misfire or a complete shutdown of the HEI."

What must be added is that these wires tend to break INSIDE THE
INSULATION. The fact that the break is hidden from view and that the
broken ends tend to rest against one another unless the harness is
jiggled just so makes diagnosis of an intermittant misfire thus
caused an incredibly difficult exercise in frustration. I discovered
my break by lifting up on the two wires about 6 inches from the
distributor while the engine was idling. When I lifted up high
enough the engine quit; when I dropped them quickly the engine caught
again.

If you are away from home and suffer this malady when the parts
stores are closed, don't despair. Slice through the insulation of
the offending wire at the distributor, then hammer a straight pin
into the wire as it passes into the distributor, bend a loop into the
protruding end, strip the end of the wire and wrap it tightly around
the bent pin. It will easily get you home. When you get home,
solder it. My "temporary" fix lasted nearly 20,000 miles.
