Where can I get the odd 12V power plug that goes into the LVQ-212 ballast?
It is a standard connector for a 9006 bulb. If you are looking into purchasing this plug you should know that the LVQ-212 should be sold with a high quality 9006 connector already crimped onto wires. If you did not get one, go back to your seller and require it. Alternatively, lower quality 9006 plugs are sold at NAPA, Pep Boys, Canadian Tire, etc. In most cases, OEM 9006 connectors from a junk yard will be a better connector as long as it is connected on the yard.
