installing controller box

[darv]

What is the safest way to install controller box without it frying up. I have a 2002 pds EZ go with a run tow switch under the seat.

Welcome to the forum.

Flip the run/tow switch to tow.
Unhook the main positive and negative cables form the battery pack.
Change the controller.
Hook the main positive and negative cables back up.
Flip the run/tow switch to run.
