you didnt need to double up those connections?
or were you showing where the points are?
Is this what you need?
You have 2 options for a return path. The module it's self, and on the driver.
Do you mean ''focusing in on the solution''?
Most green modules are case negative, meaning the brass module part can be used as the return path for the electron flow.
Does your module have just a spring at the bottom? If so that is your + side
