I just received my HID digital kit with a Relay Harness + 50W resisters. Do I have to use the Harness on my 2010 Prius III?
My relay kit came with the resistors. Basically for my setup, I ran the power cable (red) from the HID kit to the + fuse within the fuse box. Then I connected the my relay kit which consists of ground wire (black) and resistors to the HID kit. The ground wire (black) are held by bolts to the car frame.
