Ford bantam electrical troubleshoot

Before a fire hazard accrued l was
driving around and my hazards
starting to indicate and would not go
off ,my gages stop working my
bakkie was doing its own thing and
burst into flames !!! I saved most of
the pickup to find that there are a
electrical cable that’s splits to
different apartments there is a white
plastic cable insert that joins the
cable that goes into the bakkie ,can l
repair just that part of cable and by
pass that insert that burnt it’s like
30cm hat burnt and the bottle so can
l rewire those cables without the
cable connector
