Just the kit, no harness. You don't even need to ground it although I did. This truck doesn't send a pulsing ground signal.

Confirmed. Ultra HID w/ CAN-bus from DDM work without a harness. Super easyon the 2014 Silverado LTZ too!

I've been searching in this thread and I have a question about the DDM Ultra w/ CAN-bus. The cashier at the local DDM store said that I wouldn't need a harness since they have the CAN-bus with them. Am I really able to hook up the Ultra HID kit without a harness since the CAN-bus is integrated? I have a 2014 Silverado LTZ. Interesting, found their facebook post and it says it works without the cap/relay. DDM Tuning We've seen people using the regular kit, plus both HID harness + error code eliminator (BOW3), however came back just after a few month, with a killed component (normally a dead ballast). It's because it didn't really solve the compability issue. The Ultra Canbus kit is proven to work perfectly on the newer Silverado, without requiring any additional accessories!
