Picking up where the old thread ended.
I going to post the last Question here
@dev can you Swap this for the old thread as it hit the limit for posts?
What is trigger inversion
Short story, Trigger Inversion is where we make those analog Triggers accept On/Off functions of a momentary contact switch, such as Arcade push button. Called that as you are litterally inverting the signal.
Here is the OLD thread that covers this, but the images are long since been broken.
Be honest with you if you haven’t purchase your pad yet (or at least taken it apart) you are better off with a GamePad that DOES NOT have the Trigger Buttons wired as analog, like a Fight Pad or one of the Many Replacement PCBs that use Screw Terminals. The PS360+ or the Brooks Universal Fight PCB are your Best options for the mod (but they are going to cost more).
I did find an image that relates to the thread with a wiring diagram
