I have my second battery in for auxiliary stuff (lighting, winch, air etc.) but have a question about one of my isolators connections.

I have a PAC 200 amp isolator/relay. Everything is hooked up. My only question is, where do you connect the isolator terminal that is supposed to connect to the "12 volt true ignition"?? It says to connect one small terminal to true ignition power from my ignition harness.

I have no idea. Any help would be appreciated. Preferrably with a picture since I am no electrician. Thanks.

 

I think I may have figured it out. I believe that terminal simply connects to a fuse in the fuse box that is only powered on when the vehicle is turned on.

 

Figured it out.
