Wiring Conflict.

[poppywillow]

I have two drawings for an F150 with conflicting info.

The 6 pin I/O plug from the "Speed and Fuel Meter" (round) that takes the tank level info also has an NMEA0183 output for a GPS input. one of my drawings shows the :-

L wire BLUE as (+) signal.
W wire WHITE as (-) signal.

The other drawing shows it reversed BLUE (-) and WHITE (+)

Which is correct? Thank you in advance.

Sorry, can't help with that model. Assuming you're talking about conflicting info in the shop manual right? Typo? Easy enough to figure out I would think. Can't you take your multimeter from each pin to ground and see which one gives you a reading?
