My last step, is what you show with the "hot from Terminal to starter" cable above. I will need to cut the battery post end off the existing wire and put on one of the O-ring connectors to connect it to the switch.
With the kit that I bought, I don't have the isolation switch(black box) that you show.
Thanks for the info. I think I need to read the thread again to see if I will use this switch or do it a different way.
