Various sensor connection

Hello, I'd like to know where I can find the wiring diagrams for sensors like the MAP, MAF, TPS, and others.
My problem is this: I work at an auto parts store and I bought a device to test these types of sensors. The issue is that it didn't come with the wiring diagrams, and since my work doesn't involve the engine itself, I can't figure out the signal or ground connections, etc. The idle air control valves, injectors, and ignition modules are all fine, but the sensors are giving me trouble.
If anyone knows where I can find this kind of information, I would be very grateful. Thank you very much.

Here's an explanatory video of what you need.
