The 2nd generation VW modules

The smart modules do not show the voltages. It is possible to install a dumb board instead, but need to drill it to be able to screw it in.

Pinout of the 10-pin orange connector:

1	Temp
2	N/C
3	B2
4	B4
5	N/C
6	Temp
7	B1
8	B3
9	N/C
10	N/C

Attaching the modules to the motherboard: It is preferable to have some custom made sleeves for the M8 rods, otherwise the motherboard will be bending.

Using the 29mm tall spacers is actually not so great, because there is a ridge in the middle in the golf cart, even after I cut off the plastic fin:

That ridge is 20 mm tall. The dome nuts are 15 mm tall, so I added 5 mm to the 29mm spacers to become 34mm. ONLY TO THE 8 on the edges!!

Wiring

The black wire that comes out of the back panel goes to the fuse (P-)
The long red wire AND the blue wire in the protective sheet goes to B+ on the battery itself

Learning: if the third module was the other way around, there would be no need for extensions! Now the red had to be extended.

Learning: the holes for the modules should not be holes, but cutouts!
