Sniper and Trunk Battery help

those painless instructions wire that charge relay in exactly the same way as the one I have it in my schematic. They take a slightly different paths. Mine is direct to battery via CD, then Hot side ford relay, then to battery. Same uninterrupted end point as the painless schematic.

I choose to fire the relay from a switched point within the car (downstream from cutoff, cutoff thrown, switching wire goes dead) instead of direct from cutoff switch. If parked for a long period of time with CO switch in on position, having hot line from cutoff will drain the battery (relay coil amp draw).

Just a different method to skin or in this case, switch the cat on.
