Default Spark plugs

Hello everyone,
Today I did my spark plugs and I could not get access to remove the coil pack on 2 of them on the drivers side. I was wondering if anyone has done theres or has any tips, I did not see anything for the 21 is350 f sport online.

In the picture I got the far left one but could not get the 2 under the harness that is circled.

Its probably easiest just to move the harness. It is hard to say if its exactly like all the other 350s I've had that I have done this on. But on all of them I had to unclip some of the attachment points of the harness to get enough room to get it out. I just replaced the plugs on mine, albeit it's quite a bit older. But I had to move that harness over a touch, same on the 2nd Gen 350s as well. All of the engines are very similar.

This engine is similar but there are some small things different and one seems to be the harness and the brackets for it. I tried to move it like all the other videos online but those are a lot easier and can be moved, I have had no luck with my 21.
