Rewiring my EFI Magnum - 1970 Dart Swinger

Thanks guys, so far it looks like 2 votes for the left picture.

@moparlvr166 those are some good thoughts about the fan, but it's actually on an adjustable thermostatic switch / relay. I have it set to come on at about 210° and it shuts off at about 200° but since I have a 180° thermostat and I rarely drive in traffic, the fan doesn't come on very much. It's not wired through the ignition so it can turn on with the key off, so the switch just allows me to kill power to it. Sometimes the fan will come on after I shut the car off and I might want that to happen. Other times I don't want that to happen, so I hit the switch. When (if) I install AC I'll have the fan come on with the AC, but having it shut off when OD kicks in is genius, thanks for that idea.
