inch of insulation from the ends of the
wires, then install a short piece of spaghetti sleeve over each
wire end and slide back on the wire. Position the wire ends up
and slide a new gasket (5) over the wires. Tin each wire end
with solder, then insert wires one at a time into the proper pin
of connector (4) and solder. Slide the sleeve over the pin after
solder has cooled.
