Well... idk. I mean, I guess... but do you know what the 3rd wire is for? It's connected to a spark gap on the pcb (and some other stuff), and when the unit did work under my observation, it was sparking across the gap. Which I thought was odd, but idk. Maybe it uses it as feedback for when it needs to terminate the oven ignition. In which case, it'd be a coil output and there would be no continuity between it and any other lead.
But I'm just guessing here.
Also, I hooked it back up to my jug and it decided to work for like 3 sparks, and even so, it only sparked across the pcb spark gap.
