Randucci Posted December 24, 2017 I am installing some extra batteries to use on a 12v to 120V converter and will be using a Blue Sea SI-ACR isolator. The isolator has a terminal to connect the starter solenoid wire to so it only uses the main battery and not the others when starting. My question is, since the starter is buried under the intake manifold, does anyone know where I might tap into (hopefully somewhere in the fuse box area under the hood) this wire to use on the isolator? I really don't want to run a wire thru the firewall from the ignition if I can locate it in the engine compartment. Quote Share this post Link to post Share on other sites
