Don't think so. I'll check the instructions that came with
it but they're mostly in Spanish IIRC.

I just spotted it at the w/e when I was debugging my
FI problem.

Yes. If you look at reg1.jpg its the top left : simply
a threaded stud. The other 3 are blade connectors
insulated from the case.

Through the mounting bracket. In OE one there's a brown
wire with a ring connector which I put under a mounting screw.
In reg3.jpg you can see the screw for this which is part of
the mounting bracket: bottom right.

Here's the old installation FWIW.
