need help classifying some things

[iloverotary]

first my injectors
im 80 percent sure its high impedance but i just wanted to be sure
is it high or low impedance???


lastly my harness
can u guys tell if its a s4 or s5 by this pigtail plugs, this pigtail plugs are located at the old air intake box location, passenger side strut tower
or to make things easier can someone please look if they have the same pigtails on there S4


i have two of this white plugs near the drivers side strut tower, i know one is for the head light
what do this circled in yellow one plug to???

If the fuel injectors are red / pink, it's most likely a 1988 turbo?
Look at the key notch - it's most likely offset and high impedence.

If the pics are from the same car, then it's an S4.
