I have been going thru the extra parts I have and found the remains of a old wiring harness.What size wires should I plan to use when I replace the wires?I need to know what the correct routing of the wires is.I also will need to look into where to get some paint.I know this has been asked before.when i did a search,it said nothing found.Thank you for any help.I will have a lot more questions as i hopefully make progress.Rick
