Photo shown with the metal clip that holds the heated seat Hitachi plug connector removed.
Here’s the referenced metal clip that holds the aforementioned heated seat Hitachi Plug connector.
The visual view-angle of pic is mildly deceiving. I was able to run the fuse panel’s wire harness, routed as shown by the yellow line, without the harness contacting any edges of the metal clip - and secure the harness so it won’t ever move into any contact with the clip - but it sure was a lucky close call . . . so be very, very careful when you decide where to drill the hole in your trunk wall !!!
