1988 Camaro 305 Vin E TBI Wiring Issues

I have the service manuals for this car.

The diagram I have looked at shows the alternator has 4 wires 2 red and 2 brown. I have a 3 wire plug which has Red Tan/white and black but when I look at another diagram it shows it should have Red Tan/white which is only 2 wires. I replaced the wiring harness because of mice eating it up with a harness I got from a junkyard and the wires matched up except for the black I do not have a wire to use.

Can anyone tell me where the coolant fan switch is located. When I look at the diagram it appears to be near the starter but I have a white wire there for the detnonation sensor.

I also have 2 wires a bright green and a purple that I do not have anything for them to connect to.


Can anyone help me with this.

Purple is usually the wire to the starter solenoid
green wire is usually the temp gauge
