The Isolator lead for HPDI is part number 69J-81949-01-00. If you only have one battery per motor you don't the isolator lead, it's for charging a second battery.

yes i have three batteries one for each motor and one for electronics that need to be hooked up to the issolater do u have a picture of this harness? do most motors come with them instaled or is it something that you have to install

It is an optional part for the HPDI motors.
