Relays. I would not fiddle with all the wiper relays. So far as headlights, make sure you make that circuit RELIABLE. You don't want to lose lights at 70+ at night.
I WOULD ADD a relay fired by the key "run" circuit, as voltage drop in that circuit is a big problem, and affects the voltage regulator, causing it to overcharge.
I mainly did the wiper because the dk green going to F2 had ZERO insulation from the firewall through to the dash switch. I am guessing the remains of the insulation are what have cemented the other wires into one piece.
The middle red wire in the ignition switch going to the main splice area and on to the firewall in one direction and fuse box in the other isn't completely bare but has several bare spots. Even burned through the wrap.
