PCB Heatbed how to connect?

[GOC]

Someone suggested to use an SSR instead of car horn relay.

- I'll second that suggestion, just make sure you get one that can handle the amperage. I use Panasonic's SSR's in most of my projects and have had great results with them. I like using the fast switching relay's like the 211EH, but again check the amperage requirements of the bed your installing.

Another user "grob" shared this photo of the wiring.
Thought Id share it with the rest here.
