Wow, if pin 6 is ground, then I don't know how it's wired. Non-standard in that way could make things difficult. Do you have any documentation?Seems to have worked. The ground is probably pin 6 with around 0.4 ohm resistance. The rest were kilos if not mega ohms.
Pin 6 connections were: 7, 8. At least one of them should be a data pin if correct.
