You are correct there is a discrepancy. It looks like my ohm meter
is starting to read erratically. So here's a revised pinout

20 pin   19 pin

1 -------- 16
2 -------- 11
3 -------- 2
4 -------- 12
5 -------- 3
6 -------- 13
7 -------- 4
8 -------- 14
9 -------- 5
10 -------  15
11 ------- 6
12 ------- 6
13 ------- 7
14 ------- 17
15 ------- 10
16 ------- 18
17 ------- 8
18 ------- 19
19 ------- 8
20 ------- 10

Pin 1 and 9 on the 19 pin
connector aren�t connected.
