The wiring and cabling job is very tidy and impressive. That earth strap sure beats the factory shrimp!
Only thing is (and YMMV) I'd be a concerned about the battery positive being so close to the LH bodywork. The 7/9 turbos (batteries mounted on LF) have their battery terminals on the opposite sides to the NA models (batteries mounted on RF) .
But from this pic ....
... it looks like there's enough spare cable to turn it around if necessary, like if you're faced with the situation of having to use a replacement battery with the terminals on the opposite sides to your present battery.
That Projecta distribution block is $47 very well spent. Now I want one.
