Wires & Wire Diagrams

1. Two technicians are discussing a wire harness construction: Technician A says that connector #1 is the male connector because the while plastic connector fits inside the connector #2. Technician B says that connector number #2 is the male connector because it has male terminal pins inside. Who is correct?

technician A only.
technician B only.
both technician A and B.
neither technician A nor B.

 

2. In the GM picture shown below the "170" represents:

Black with a red stripe.
Blue with a red stripe.
Brake light harness, right side.

 

11. Technician A says two connectors with the same number are physically the same connector. Technician B says the two connectors are drawn apart so that the drawing is easier to read. Who is correct?

A only.
B only.
both A and B.
neither A nor B.

 

12. The number outside the Toyota symbol shown below, indicates the:

Connector number.

Pin 10 and pin 3 only.
Pin 10 , pin 4, and pin 3 only.
Pin 12, pin 13, pin 5, and pin 4 only.

 

14. An electrical circuit has a large voltage drop before the load. Technician A says a loose terminal connection could be the cause. Technician B says that broken strands in the cable could be the cause. Who is correct?

Technician A only.
Technician B only.
both Technician A and Technician B.
neither Technician A nor Technician B.

 

15. In the Toyota wiring diagram shown below, the "B" in the splice code indicates the splice is:
