Installed msd ignition box and dizzy. Now wires under dash try to get hot

Hot amp meters from to much current going thru them have caused fires. Somewhere on this forum is a schematic for wiring in a relay triggered connection between the battery or alternator ( @67Dart273 correct me here) and the voltage regulator to limit the overcharging caused by voltage drop. I’ll find it when I get back home and post it.
