One Pair of Resistors
For Single beam kits without relay harness: connect into the input
of the ballasts and mount gold resistor to metal of vehicle.
For bi-xenon kits without relay harness: connect into the input of the
ballasts and mount gold resistor to metal of vehicle.
For Single beam kits with a relay harness: connect into the input of
the relay harness and mount gold resistor to metal of vehicle.
For bi-xenon kits with relay controller harness: connect into the
input of the relay harness and mount gold resistor to metal of
vehicle.
Connect right before the ballasts if you do not have a relay
harness, If you have a relay harness you will need to put one
before the input on the relay harness and the other on the other
factory lamp.
