can’t find speed sensor on 2003 ram qc

I need to hook my GPS to the Speed sensor wire. On the digrams I've found from this site it should be:

SPEED SENSE|WHITE/ orange        |   |wht conn. 2, pin 27 @ PCM *5|

So when I checked it out. and unplugged the White conn. #2 I only have three white wires... White w/ pin red, White w/ pin brown, White w/ pin blue.

I had my wife come out and confirm the colors, since the brown and the red could be taken as orange, but when comparing to an orange wire it wasn't the same.

I really do appreciate your guy's help on this, I've been stuck on it for a while now.

Thanks

Speed Sense	WHITE/ orange		conn. 2, pin 27 @ PCM
The PCM (Powertrain Control Module) is on the passenger side firewall. On the 4.7L motor, the VSS is WHITE/ orange in conn. 1, pin 13. On the 5.7L motor, the VSS is dk. GREEN/ YELLOW in conn. 1, pin 13.
