seventh injector does not work

you know how it works on the seventh injector?

It takes the signal from the bulb?

There is a relay?

the collector there is a brown color temperature sensor, (some blue models) does not seem to get current, even if the car starts off, and if the attack does not change anything, you know what serves this sensor?
2) there is also a sensor with two pins, no current, slightly behind the first, you know what is it?

how can I enter the picture ??
thank you
