Based on your tests and the datasheet I found, it's clear that either R66 or R68 is the common wire, the other one is card detect. That leaves R67 for WP. Write protect goes active when it's unlocked per your probing, and because when the card gets inserted R66 is always in contact with R68, doesn't matter whether you connect R67 to R66 or R68, either should get the job done. |
