Modifying an el wire inverter

I read this post on Instructables about how to modify an el wire inverter to make it have one mode instead of 3, but my circuit board looks different than the example and I don't know which solder points to bridge. The article is years old so I can't get an answer from the guy who posted it.

Here's the Instructables link:

Here's what my circuit board looks like:

Which solder points do I bridge?

Without a schematic of the Instructable one and of yours, and component layout diagrams for both then you are simply guessing. Good luck.
