Ah yes........This post reminds me of my high schools days when I ran a small boombox off the interior dome light. The boombox ended up catching a small fire which left a smell that never came out.
I just read through it all... Wow. Did the owner of the car know about the car fire waiting to happen? Glad to see you did it right. In my opinion if it can be returned to stock OEM without having to order new parts, it's not modification. At least not major modification.
