And I have yet to see any automotive diagram with a mosfet (what the **** is that?), transformer, logic gate (WTF?), or rectifier. Rectifier sort of sounds familiar though, maybe logic gate does to.
But all the real complicated stuff is inside the computer. Mechanics don't fix computers, they just find out which one is broken and than replace it.
Rectifiers help you go from AC to DC. You can use a full wave rectifier with a smoothing capacitor and create a DC voltage.
Mosfets act as switches with a thresholds. Most tend to not operate below 0.7V, once you go above 0.7V the fet is turned on and you can control various devices.
Transformer, either a power up or power down. You can yank say a 12V source to 24V or yank it down to 6V.
All those are inside your car, somewhere deep in there.
