Where can I buy a relay harness? I'm doing the fogs, hi and low beam. I have spyder auto aftermarket halo projectors (if that helps). Can I keep my ballasts I have now? If you could link me that would be cool. Will an eBay relay harness be ok? How many harnesses do I need for what I'm doing? And last but not least do I need to solder stuff, because I can if need be :-)
