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

btw thank you to all who help me in my past/future posts...

 

your engine harness is s4 (black cylinder plug is for VR) body harness ? I would guess matching. those plugs by the pipe are your headlight motor (white) and the two small black are your corner and front turn signals.

to find out on the injector impedance if the notch for the plug is in the middle they are low and if it is off center they are high.

 

i have two white plugs, i know one is for the head light but the other i dont kno, do any one know???
btw i found this article about the 2nd GEN rx7 injectors
idk if its accurate but here it is

Take a multimeter, measure the resistance if you are unsure. Anything lower than 10 OHM is low impendance...

 

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???
btw it comes from the main front harness

 

Please don't bump your posts, especially after only an hour.

I believe the white round plugs are the headlight motors. You can check the wiring diagrams in the FSM or Haynes (Haynes is often easier) and confirm this based on the wire colours and harnesses the plugs are attached to. ECU = Emissions (EM) harness, starter = Engine harness, body harness = Front harness in the manuals.

What is the part number of the injector? It is stamped onto the plastic lip. Just compare it with the injector list in the FAQ to know for sure.

 

btw the plug that i circled in yellow runs to the transmission and bottom of the motor near the oil pan where do they plug to???
