A: Only if you have an extra quality comparison. Toyota updates the wiring slightly (moved the BTS resistor, changed the aux relay logic). You need the schematic that matches your unit's serial number range. toyota pz071 wiring diagram extra quality
Often Pin 21 or 22 (depending on the specific sub-model). SW2 (Signal 2): Adjacent to SW1. SWG (Ground): Common ground for the steering resistors.

harnesses, which are notoriously difficult to find in standard repair manuals because they are sold as "Accessories" rather than factory-standard parts. Often Pin 21 or 22 (depending on the specific sub-model)
While specific colors vary by vehicle model (e.g., Hilux vs. Corolla), the 16-pin or 24-pin connectors used in these harnesses generally follow this logic: V+ (6V or 12V):
