Hi all,
I have had my W210 1996 E320 since 10 days and would like to understand more about the engine M104.995.

Please help me identify the components in the picture below. I removed the air cleaner and all engine covers for more visibility.
I got so far, admittedly mot much
0: transmission fluid dip stick
1:
2:
3: MAF sensor
4: Ignition coil
5:
6:
7:
8:
9: Oil cap
10: (don't know electrical cable to what?)
11: (don't know, looks like injector - red part under wire harness)
12: (don't know electrical cable to what?)
13:
14:
15: (don't know electrical cable to what?)
16: (don't know electrical cable to what?)
17: thermostat
18: (don't know electrical cable to what?)
19: (don't know, looks like AC hose)
20: (don't know, looks like AC hose)
21: throttle body intake
22: air intake magnifold
23:

25: ABS
26: Windshield water container
27: Coolant hose
28: Coolant hose
29: (don't know, it's a black container for fluid, maybe power steering fluid)

I'd appreciate it if you could name the components with their number.
Besides where are the spark plugs, near part # 11, 12?
