Sounds good, the 12 seems large , guessing its due to fuse box buss bar connection the way done 44 years ago.
One day I need to go thru my wiring harmesses, the body is a 73 and engine 68 so there are a lot of extra wires in the engine compartment, duplicates of some , haha.
Been following your build , not sure about me wanting to do a complete wiring project , but do want to get the headlight relays installed at least.
You are able to upload photos a lot , do you have to resize , I always have trouble here using ipad.
