MSD6AL box compatible Distributors

Hey guys. Are most electronic distributors compatible with the MSD boxes? I see many with 2 wire outputs.

Currently running with MSD 6AL with an MSD Billet (now Im broke lol).

I am contemplating buying one, but I have no idea what kind of curve I’ll need until I start doing it myself looking for something inexpensive that will give me decent reliability. I’m just wondering about the compatibility. I’m planning to do my own curving based on my needs.
