We had an old Avcon available so we upgraded
it to the new J1772 connector.

The pictures posted below outline the process
we used to complete this
upgrade.

Avcon  ICS-200
Avcon  ICS-200 original
cable with original
connector.  This cable
was 24' long, but we
shortened it to 15' to
improve ease of use
issues.
The new 75a J1772
connector opened up.  
We chose to epoxy the
proximity wire & the
ground wire to keep
them out of the path of
the HV wires.
The original Avcon
cable is made up of
four (4) wires including
HV 1 (black), HV2 (red),
HV ground (green) and,
Pilot (blue).  The cable
also has a white strain
protection nylon cord
system (not pictured).
We removed the outer
insulator for 4.5" back
from the pin assembly
as pictured.  This also
shows our cord retainer
clamp estimated at 5.5"
back.

removed.

Note the white strain
protection nylon which
will be folded back
under the cord retainer
clamp.
The two (2) phillips
screws shown here
release the pin retainer
assembly to access the
pins.

retainer assembly.
This shows a pin as we
approximate the lenght
of insulation to be
removed from the wires
for soldering.
Note that the connector
ground wire is now heat
shrinked with the HV
ground.  This process
helps keep the wires
aligned for soldering.

Also note that the pin
retainer is in place
before soldering.

The cord retainer clamp
has also been addred
to hold the work in
place as pictured below.
Pin soldering
completed.
Final fitting.  Note that
no wires are crimped
and everything flows
properly.  This also
shows the ground wires
heat shrinked together
and its benefits.
I was not happy with the
way the two HV lines
were routed against the
connector / proximity
switch so we added a
piece of HV insulation
to create a buffer
between the
components.
