You can use this larger white wire to the fuse box in place of the black/blue wire by doing the following:

• Cut the SMALL WHITE WIRE AT THE RING TERMINAL that was on the B+, leaving the larger white wire on the ring terminal. Run this large wire over to the fuse box, routing it the same way the black/blue wire routes, disconnect the black/blue wire from the fuse box and replace it with the larger white wire (you'll have to bend the ring terminal 90*, and lay it UNDER the mounting tab, to replace the screw).
• DISCONNECT THE BLACK/BLUE WIRE AT THE FUSIBLE LINK OR IT'LL STAY HOT. I contemplated leaving both of these wires connected to the fuse box, but figured it was unnecessary, and very very remotely hazardous should the box somehow draw enough to blow one fusible link but not the other.
• Crimp the smaller white wire in the new ring terminal along with your new large gauge wire going between the Battery (through a fuse) and the B+ so it'll continue to feed the components in the fuse box as it did before.

I don't know if this larger white wire to the fuse box will yield any noticeable results in brighter lights or louder horns, but it seems like a waste not to use if for something. You could even now use that black/blue wire to power something else if you like, or just disconnect it and tape it off as I did for future possibilities.

You should replace the black/blue strip wire with a larger gauge or run a parallel same gauge in the section which goes from the engine fuse box to the ignition switcher since this wire power several accesories which are on, in the accesory position or the ignition position, one of them with a high current demand in the ignition position is the power windows (of course the contacts inside the ignition switch should be in good condition and not overheated or pitted).

You will notice right away an improvement in the windows speed when rolling them up.
