I removed the trunk panels yesterday to gain access to the ignition coil section and also to place some Second Skin Heat Wave Pro as I'm trying to reduce the trunk temperature from reaching 300 degrees (to maybe 250 degrees?

).
Regarding the ignition coils, I found that, the wire harnesses are indeed exposed to water getting in due to their placement and orientation. I placed some heat shrink tubing on some of the wire harnesses and battery silicone covers on others to better protect them. Nothing is glued or permanent, only heat shrink tubing and zip ties to seal and hold them in place, so they can easily be removed should there be a need to replace any of the parts in the future. I hope this could help avoid future water damage to the ignition coils and related harnesses. Here are before and after pictures.
