hi all I have an issue installing some HID's I bought im not sure where to plug the harness into the factory harness (2013 d40). Ive chased back the earth's from the drivers side headlight to a plug next to the battery which must be the headlight relay (cant chase the power cable as is in a separate harness that goes under my battery tray) My concern is there seems to be about 20 other wires which also go to that connection. I don't want to plug it and blow something up. I had a search but HID and Install came up with 50pages of resuts and after 2hours still couldn't find it. If anyone has some pictures or advice any help would be greatly appreciated.
