the black protective sleeve is designed to be removed from
the connector. You can use a jeweler's screwdriver to remove
it. This black protective sleeve is the only one on the fuel
injector harness which this connector is attached to, so that
should make finding it easy.
Once the grommet/seal is removed, this is what you see:

wire.
This is what happens when you apply a soldering iron to this
insulation:

the insulation. The correct high-temperature insulation would
NOT have melted.
