I'm going to use a hot-rod type of block and harness, should be easy.. that, or I found a wire manufac. that provides labeled wires... this means I can have black for ground/negative, and red for positive... while the circuits are being numberd on the jackets.. so, if I have a problem with the power to the rear lights, for instance, I would look at the number on the wire, then find it on the fuse block, etc..much easier for troubleshooting...
oh, I'm also going to make a run to the junkyard after the runs are made, but not terminated.. I'm going to get both ends of a harness connector or two, maybe 3.. from the engine compartment of a modern vehicle.. this will allow me for ONE disconnect to remove the hood, ONE for the body, etc.. very handy!

you must have pride....in your ride....
