yellow wire is oil pressure. the other is the fan switch, only the T2 and automatics have it, but every car has the plug

The Y/R wire of the sender comes from the Engine harness which then connects to the Front harness. Both Front and Emission harness wires "can" run to the ECU, but some don't. There's a Y/R wire at pin 1B but this Y/R wire goes to a Green check connector plug w/two other Yellow wires and a B/W wire located near the leading coil. If you believe the wire in the pic goes to the ECU then a continuity test should prove that one way or the other.
