I was wondering if anyone could tell me the source of the wires that go into the front harness side of the front harness to emission harness connectors for an 89 N/A. I believe the connector names are either fem-01 and fem-02 or x-10 and x-11. I have heard both. Again i just need to know the source of the wires like (trailing ignitor, ect). If anyone can help me i would appreciate it. The FSM on iluvmyrx7 has a detailed schematic for the s4 but a vague schematic of the ecu only for the s5.
