Exactly what I needed, I will be rewiring in the next 2 weeks when I get back home from my real job in the frigid frozen far North of Alaska.

Thanks much sir.

is there a color code or wire size chart for the wiring ?

Not to my knowledge--if we replaced any wiring we simply used what we took out and copied the colours and sizes from old wires--they are very basic.
Cheers,

Once again, Thanks mr. the knowledge and info available here is outstanding.

you can make a simple code using a fine tip permanent marker and a series of dots and dashes. (which is how its done in most cars anyway)

and remember grounds should be white or black. and use different colours for different circuits.

a dymo tape label machine is handy as the tape can be easily stuck back on itself. and being printed are easy to read
wire should be tinned before ends are crimped on, better yet crimp & solder the ends on, use resin/rosin cored solder
a dab of tail light bulb grease helps conductivity and keeps moisture out of the connections, prevention is better than cure
