Gauging interests - plug and play Headlight relay kits

What would one cost in all 12 ga wire with relays mounted under the battery tray?
Does it come with the ends for the lights or would I have to add on my old ones?

Around $140 + shipping is what I'm thinking. I know how long it took for me to make the first one and do it cleanly.

It's a complete kit and you use none of your old headlight sockets for powering the headlights.

The bottom pic in my first post are the runs from relays to headlights with the ceramic sockets attached. The other wire pair is from alternator to relays before fuse holders are added.
