Is the starter kill in question a "On board" relay in the unit or a seperate relay ?
If its a on board relay then unpluging the harness' from the unit would not work without jumping out the starter wires to re-join it.
Not all, Starter kill / Anti grinds are passive some are active meaning that they are wired normally open.
80% of these kills are wired normally closed but there are some that are wired as open.
We need to get him to verify that the 2 sides of the starter wire go to a seperate relay not to an onboard relay like 2 black wires coming off of the unit.
Better yet just re-join the Starter wire.
