Hello Added a second battery and the Isolator has the option to use the second battery during cranking. Is there an easier way to get this hot cranking signal other than pulling a new wire from the starter relay? Has any one found the wire under the dash area? Battery mounts in the tray to the aluminum fire wall that I added and Isolator mounted to the frame. As you can see there is a ton of room under the cowl. I ran mine long to cut down on the hot air and dust.
