Hi Rob and it depends on which isolator you have.
The SC80 is still the standard isolator it always has been but I have been supplying the new USI-160 isolator for about 18 months now and it is still a case of which isolator you get for what operations you are going to use it for.
The SC80 is still the best isolator for fit-n-forget set ups.
The USI-160 is intended for vehicles where electric winch operations are going to be carried out.
