Correct wiring for Dual Alternator Controller

I am installing a SARV3 with a DAC. I have two conflicting sets of instructions(Dual Alternator Wiring Diagram). The first one shows the DAC pin#9 connected to the SARV3 pin#6(alt gnd) The second shows DAC pin#9
connected to pin#3(gnd) of the SARV3 Which is the correct diagram?

They are both the same. One has pin numbers, and the other has labels.

You are correct, but the one with pin #'s shows pin#3 and the one with labels shows pin# 6! Are you saying that it doesn't matter(that pin 3 and pin 6 are the same?)

OK, I see the problem. It proves the old adage that information which exists in two places is wrong. Or a man with two clocks never knows what time it is.

Download a new copy of the DAC manual and follow it. Look at the table in the text that correlates the signal names on the wiring diagram with pins on specific regulators.

I could not find a DAC manual on your web site! I just need a knowledgeable person to tell me, pin #3 or pin #6 . This is very confusing because the wiring diagram on both sets of instructions is dated 2003. The SARV3 manual dated 2009 shows the DAC wired to pin #3 while the "updated" version dated 2005 shows the DAC wired to pin#6 !!!!
