Okay, if I am understanding you right I did the following based on pinouts above:

Grounds to grounds, 0 ohm as expected:

Each 5v to 5v ground, 45ohm give or take 2

12v+ (pin 1) to pins 6 or 7, 165 ohm.

Pin 1 to 8, 492 ohm

Pin 10 to 6 or 7, nothing with negative at ground. If I put positive to ground, 566 ohm

So from that, if I am reading things right, seems okay?
