When adding the EGR back into my swap, I noticed two different gray wires. I just want to make sure I got them connected back correctly. The picture below points to the pin where one of the gray wires connected and reads 5V when the ignition is turned. From what I understand, one gray wire (pin D) should be the 5V source and the other is a common voltage point for several things (pin B?). On the picture, the two gray wires lead to pins 2 and 4 going left to right (I don't know what letter pin corresponds to what real pin). Any help is appreciated.
