Adding a heated bed: step by step guide?

Does anyone know of a step by step guide to adding a 3rd party heated bed? I’ve done a search and found bits and pieces, but nothing comprehensive. I have a 12v heated bed that I’d like to use, and I know I’ll need a relay, but that’s about where I get stuck.

Let me use the search function for you: :wink:

In short words: no step by step, do your own, it isn’t that hard…


As I noted in my original post, I did search, and I did not find a step by step guide, which is why I asked. I thought perhaps someone knew if an off-site resource.
