Updating the wiring harness on the 69 GT

Ok so like many of you the wiring harness on tie car is another example of the level of Butchery, house wiring nuts and wires wrapped around terminals etc. So I am planning on all new harnesses for up front at least for now. I have used painless and American autowire in the past on hot rods etc but I want a completely stock plug n play harness any recommendations?
