Package received from Taiwan! - Toyota Yaris Forums

positive trigger = a +12V wire is given power when the switch is on.
negative trigger = the ground wire is active when the switch is on.

toyotas are mostly negative triggered. Makes the harness a little different for constructing.

The high beam will get the common 12V and the high beam ground
The low beam (HID) will use a relay harness which will use the low beam and high beam grounds as a trigger wire.

Black Yaris, what are city lights? Do you mean the parking light? Is it a bulb that turns on when you flip the headlight switch one notch, and stays on during the low-beam switch?

what you are calling a positive trigger is a normal neg(-) ground system
what you are calling a negative trigger is called a pos(+) ground

City lights are the these, I had this pic laying around, to explain city lights to someone else
