So as I read this thread, trying to summ it up, the process would be:
1) flash truck back to stock
2) turn on the headlights
3) disconnect both batteries
4) short out + to - cable on both batteries,
5) leave truck sit like this for 3-5min
6) connect everything back up
7) take truck to Ford for whatever work inspired doing this
That about summ it up?

I have not looked at the wiring specs so am guessing when you say I don't need to short out both batteries that means they run more in parallel then in series? IThinking as I type I guess that makes sense as we don't run our trucks at 24 volts ... do we? (pardon the newbie-ness as this is my first diesel)

Bob, I do hope you're not suggesting paralleling the clamps on one battery only while the other is still attached? I think it might be prudent to insert a giant warning that this should only be done AFTER BOTH BATTERIES HAVE BEEN DISCONNECTED.
Unless you like letting the magic smoke out (and, believe me, they pack a *lot* of smoke in dem batteries!)

What if truck was flashed back to stock 6 months ago? I had the Predator, took it out, and put truck back to stock. I never disconnected batts, etc. Does that mean evidence is still there in the pcm capacitors? If I disconnect batts., etc. now will that clear everything?

Nitpick: Data is not stored in a capacitor. A capacitor stores charge... which keeps part of the memory "alive" (refreshing) thus potentially storing data. </pedant>
You never know... I'd be tempted to rip the clamps off and let it reset, just in case. Better safe than sorry.
