So I got a set off DDM Tuning slim ballast HID H3 kit for my fog lights, but I'm not sure how to install them. It appears I have to run the wires through the back and to do so I need to drill the hole bigger. Can somebody confirm this? Also can somebody take a look at the pic attached and tell me where I need to hook each wire to? There's a black and blue wire with a spade connector and then a pigtail connector.
