I used a Dremel heavy duty cutting disk on medium-low speed and made several cuts to the harness plug until the unmodified H9 could fit all the way in. No knife needed, just Dremel, inset bulb, test fitment and repeat a few times. Literally took me 30s-1m per side (I did the h11 fogs also to store 2x spare H9s).
Thank you! Very helpful. I have cutting disks from my son's projects in the past so I think I have everything I need now to finish the job.
