    Helping identifying electrical connections

    As I put this thing back together I’ve got a few labels that fell off and need some help identifying. Plus I had the bay resprayed so I’ve got some that may be misplaced.

    Here are the first two...

    One is by the mid fender relay box with cover and is in the same harness that leads to those relays.

    Second is tucked up by the fuse box. I think it looks like something that should be in the front of the car but maybe something else.

        Hard to tell from the pic, but the first connector looks to be the harness for the AFM on the air box

          You are right! Since I’m using a standalone, I’m not using anything from the OEM afm/intake so that makes sense why it’s not there. Thanks’

            Second connector goes to the headlight assembly I’m almost certain

              I'd say second connector is for the factory alarm horn.

                This one is by the ECU and can’t figure out where it goes. Any idea?

                    The wiring harnesses were designed for the whole e30 range so there are some plugs that don't plug into anything on your car. My car had two plugs like that in the ECU area and one of them plugged into the engine wiring harness while the other was just left unplugged.
