Okay so, you're talking about the pink wire coming from the fuel pump area. I only see 1 pink wire and one other grey wire besides the Fuel Pump feed wire which is also grey. I think what you're seeing is the pink and grey wires that are for the Fuel Gauge. The A58 connector doesn't have any pinout unfortunately. I've looked everywhere and all I can find are these two diagrams (1st 2). In the 2nd diagram I believe that is the A58 Connector coming out of that panel on the driver's side. It's the only 12 pin connector that matched up. But I don't think that is what you are looking for. The third diagram is the Fuel Gauge sending unit to the instrument Cluster. Thats the big purple colored component to the left. The gauge wires run through the J/B 3 connector. Finding that J/B #3 was really tough, but it's up on the driver's side, looks like it's more up above the gas pedal area. The 6th diagram is the fuel gauge circuit it's the OEM from Toyota, and not very helpful. But you can see where that pink wire goes and what it's for. And on the seventh diagram are the pins inside the instrument cluster for pins # B15 and B16 which is the fuel gauge circuitry. So, it should have 12volts going out on one of those wires and then you can see on B15 it has a resistor coming off that circuit inside the cluster, so that would be a voltage sensing circuit coming off that resistor for the gauge reading. Hopefully this all will give you what you need. Sorry it took a while to find all this.
