Phew. Nice install method.
So I have to admit I read the DIY and did the install without reading the complete thread. It's summer so I didn't even try the roof until reading this a day later.
Good news, no roof issues. I made my own invisicord as I had one from the infiniti g35 I had previously. The little pin connectors work nicely.
I admit I would likely have opted for a fuse tap if I read about the roof problems, but they seem attributed to bad grounds.
No problems for my bel vector 995.
Thanks for the DIY post!
