which wiring harness I should get? 9006 or H7?

Hey guys



how is everything going?



My car came with H7 halogen headlights and I retrofitted to D2S projectors and HIDs.



It was direct plug and play, and I am thinking of getting a wiring harness since my hid dims pretty bad.



Now which wiring harness I should get? 9006 or H7?



I know all connects are 9006 but since my original bulbs were H7 I don't know which to get.



Please give me an advise. Thanks in advance.
