I can't see any feedback type wiring in the ESOF clutch circuit that would signal the GEM to not do the 4H shift if the clutch is not energized...but that's not to say that there is some internal circuit-watching going on inside the GEM.
The only thing I've found on the ESOF relay locations is that on the Super Dutys they're supposed to be mounted on the driver's side inner fender under the hood. I know there are relays clicking under the dash of my '97 F150 too when I shift so I still think they're under the dash some darn place. I suppose a call to the dealership might get you in touch with a tech that'll tell you the location too...unless they are just hell bent on getting you to bring in the truck so they can get a service charge out of ya.
BTW, I found the electrical and vacuum diagrams for the '97. Check your email, they're on the way.
I got the diagrams, thanks a lot.
As for calling the dealer...no luck I tried 2 different ones here and they both say I need to bring the truck in. They gave me the same thing about the window issue I had a while back.
They want $88 to hook up the truck to tell me what's wrong with it. It would really suck to give them $88 to tell me it's a relay.
