The Retrofit Source

Wiring up a bi-xenon projector retrofit is often one of the most confusing aspects of the conversion. Make your life easy with the TRS Plug n Play 9004 Bi-xenon wire harness.

Harness has 7 easy connections to make your setup fully functional.

Outputs: 2x HID ballasts and 2x bi-xenon projector solenoids.

Inputs: 9004 factory headlight socket, positive battery terminal, and a ground source.

Uses a replaceable and compact bi-xenon control box to ensure that your HID ballasts stay on when you flip on the high beams.

Positive input cable utilizes an inline fuse for the safety of your HID equipment.

Wiring is all covered in black "high heat" convoluted tubing for protecting the wires, which are all guaranteed to be long enough to fit all applications.

Our harnesses work with both positively and negatively switched original headlight systems

1 year worry-free replacement warranty on all electrical parts/wiring.
