Acquire a pair of Spal FRH relay harnesses. They come with fuse holders and a generous amount of wiring. They are available on Amazon dot com.
Referring to the above drawing, see where the pink wires attach to new relays? There's a splice somewhere in that circuit.
See the new heavy gauge power wires connecting between the ammeter & the ignition switch? That's one possible connection, you could connect directly to the battery positive terminal also.
Everything "to the right" of the fuse box and below the fuse box is new wiring, abandon the old stuff. I mounted the fuses in the front trunk, in the front of the trunk, just behind where the oem fuses were mounted. Mounting them in the front trunk keeps the wiring & relays out of the elements. That was my preference. The SPAL relays are sealed very well and could be mounted in the oem location if that's your preference.
Grounding the fan motors and the temp switch requires a bit of additional wiring and some crimp terminals.

I am extremely electrically challenged. You say, "everything to the right of the fuse box is new wiring" however the diagram shows the original Pink power wire coming out of the fuse box to terminal 86. I am going to run new power directly off of the battery (fused). Do I still include the original pink powers in the new relay circuit as shown in the diagram?
