Weather proof connectors

[rallystyle]

I am going to rewire both of my cars with a AAW harness set up. I was looking to use some weather proof connectors for the lights as well as running some grounds to them so they don't have to worry about a ground problem with the lights. i will be using led lights so there will not be a heavy amp draw. Deutsche connectors are nice but get expensive fast. hoping to find something that has a mounting option. any suggestions on what would be a good group / brand to use? thanks
