I just ordered a HID kit from HID Extra but do I need to have a canceler for my 2007 Silverado or will they work correctly with the relay and not need the canceler? This is the first HID kit that I have every installed so thanks for the advise.

 

If its a kit it should have everything you need for there setup every system msg is different when ordering you put year and make your ok

 

i put the year make and model so hopefully ill be good or else ill be ordering a canceler also..lol
