Lee01,
Nice clean install of the window wiring. I'm sure you had no problem hooking it up as many times as you re-drew the circuit. You probably had bad dreams about that drawing.
That's where I plan to put the relays as well. Protected from the weather (meaning not in the doors with the motors which is a possibility) and easily accessable in case you need to get to them. I'm thinking I will leave enough wire that I can pull the relays out from under the console to make access even easier. I'll just have to see when I get there.
I'm very excited for you that you got the circuit wired up and working. Good job !!
Are you going to do the power locks with relays as well? I have the schematic. As I said before, it's just hand written so it's not pretty but you're welcome to use it. I can take a pic of it and email it or post it either one.
