HBC3200: Thanks for the tips. I would also put #4 as #1 on your list. I have rewired more vehicles than I care to count and that is all good advice.
I specifically got the 22 circuit harness vs the 12 so that I can have spare fused lines for future project. At the moment I only have 10 on my list, but I might add more things down the road and it is easier/cheaper to add the capability now.
If the weather holds, I will hopefully get this done over the next week.
