Steve - I hope you were successful! I decided to revisit some solder repairs I made without the aid of a magnifier.....found a couple that might have melted the coating under the solder. I have those repaired and ohmed out every pin to a common point on the board. I reinstalled the Link about 20 minutes ago and the car is still idling as I type this. I have not wiggled or drove it yet, I am going to see how long it stays running. Fingers, toes and eyes crossed here.......
