9003 Harness

So does anyone know which pin is the ground, the one for high and the one for low?


also when high beams are on, does the low beams stay on also?


thanks!

Im on my phone and trying to make a harness diagram with text so bare with me.

| _ |

This is the harness assuming that youre looking at it with the middle pin at the bottom.

Red = ground
Blue = low beam
Green = high beam

I had to find this out when installing my HIDs because it had no high beams and had only 2 pins to connect to the harness.

it should be one common ground and two positives, does the low beam have power when the high beams are on? need to rewire a HID kit, telescopic =D

The yaris uses constant positive everywhere.. and a switched ground. You can basically tap into any wires in the car if you are lazy to add a fuse for whatever you are doing. And then use the ground point of your choice....
