No, I have a kit for H11 installed now, but got new headlights via warranty. They didn't have my old style housings so had to get different ones that take H7. The H11 bulb and H7 bulb are very different in the connection wires needed. I want to buy a cheap H7 HID kit to obtain the amp wires that fit the new H7 bulbs needed. I want to continue to use the HD relay and ballasts I have installed now. Can I just steal the H7 bulbs and the immediate connecting wires to bulbs and expect them to fit my existing HD harness? Morimoto site labels HD relay harnesses by bulb size, but they are all pictured the same. Other sites label one HD relay harness like it's one size that fits all. I thought the fit was by bulb to housing and wires behind bulb to HD harness, but beyond that imediate behind the bulb connection all else was interchangeable. I see they are all different going by Morimoto site, but not sure at same time. Why would they go thru the trouble to list the HD relay harnesses all by bulb size if it doesn't matter? So does it?
