1999 E350 superduty 7.3 van....Getting started on my Np273 E shift wire up. While pulling pinouts for everything involved, I discovered a few odd items in the PCM.
Pin#4: "drive line disconnect"
Ive been looking for a clean source for a neutral gear signal and keep coming back to this. interestingly, on the F series, this spot is a "neutral gear switch" So whats the driveline disconnect circuit?
Pin#14: "4x4 tap"
What do I hook this to to get 4wd??? that would have saved me tons!
But seriously, could it be that the pcm is programmed for 4x4 indicator lights or the like?
Pin#19: "CTO Tap"
I believe this stands for 'Clean Tach Output' which would also be amazing.
