two red wires on D37 Harness for EMS


I love flying!

I'm wiring an EMS D37F harness and notice that there are 2 red wires in the harness bundle.  Because the harness is pre-wired to the D37 connector and closed up, I can't tell which of these red wires goes to pin 1 (Battery Voltage input) and which one goes to pin 15 (fuel flow power).  One of the red wires was twisted together with a black wire and the other was separate.  The wire color and pin assignment table I'm referencing is table 39 in the Skyview Installation manual. I happen to be looking at rev AC but I think it's not changed in the earlier rev's.  Which of these red wires is the pin 1 wire?
