linelock and 2 step, one button?

gumper said
I have two line locks, one for front and one rear. I use the front for burnouts, and both when staged. The two line locks are connected to a button which also activates the two step. There's a total of 3 switches to separate the front line lock and both line locks with the two step.

I had to read this slowly and draw a map to fully get it. but i got it! I like it!!! How much amperage does a line long take? In other words do you need a relay at each line lock or is it just hard wired?
