Looking for some advice on the rear mount shut-off switch, recently my brother and me changed up his wiring on his rear mounted battery to try and avoid charging issues since the guy before him didn't take it into consideration when hooking it up. To me something still doesn't seem right with the starter wiring, since the starter sounds like it hangs on for about 1-2 seconds after the car has started. My brother said the starter has a crank sensor wire but I'm not sure if we did this right. any help would be greatly appreciated. I drew a sketch of what we did. Again this kit was pieced together from exisiting parts on the car and a frankensteined jegs battery relocation kit.
