Well made & free of charge.

January 13, 2015

It was included free of charge as part of my HID kit but not required on my 99 A4 so it wasn't used. The harness is well made and looks like it would last over time.

If you have a newer Dodge, you may need to buy this with your race sport HID's otherwise you'll have flickering and your headlights will turn off.

Awesome product!

September 18, 2013

The bundled package i received (Race Sport Accessories BALLAST-CANBUS-G2(PR), Race Sport Accessories 9006-6K-SB-RB, Race Sport Accessories RELAY-HARNESS) all work wonderfully! Awesome product and easy to install on your own. Only item of concern or preference was length of the relay harness cord could have been a tad longer, but not a bad issue to affect install or use. If you get the ballasts and lights, DEFINITELY worth your money to get the relay harness! Ive had both set ups with and without and with the relay they turn on every time without hesitation.
