Thanks all,
I found a source, they are sending out "samples" in 50' lengths for FREE!! They have 10 primary colors and the same in a striped version. I will be using #16 SXL high temp wire, and #14 and #8 for grounds and Power. My father is a PE so I have that in the bag and I have top end Meter (dad made me learn years ago when we restored up my first car ever (68 coupe).
Does anyone know where I can find OEM connectors. I really do not want to splice in bad ends if I can help it! I have a source for water proof connectors now, but that old stuff is very hard to find!
