I did just that, unplugged the capacitor completely and flipped over the input wire and worked great. Had a little buzzing at first but noticed I had a loose ground. Now it works perfect and is super bright!
i just recently bought the retrofit morimoto 50w full kit with the canbus and relays. I couldn't get it to work on my 2014 denali for it would just flick and never come back on. So now trying to send back to retrofit and they want to restock me for something that doesn't work. Just a heads up to anybody looking to buy from them. So now to try something else, anybody have any ideas!
