If you don't have a soldering iron or don't feel comfortable soldering, you can get this done with circuit test hooks!

Just make sure there's a firm connection to either the leg of the voltage regulator or the leg of each diode depending on the connection you are making.

You will find these under names such as mini clips, SMD IC spring hooks, test leads for logic analyzer and such.

These are usually rated for 60v / 3A so they will do the job.
