alright before i posted i have done hopefully alot of eliminating

this was a big project but long story short no check engine lights bc i have yet to start new engine.

hook batteries up and i hear the fpr continuously buzzing along with my relay for ignition clicking. key is off and out of truck. Radio does not work, cluster does not go out, oil pressure is pegged like its being back fed somewhere, no ac controls or anything inside the cab work. Ignition does crank over and then stop as it is suppose too.

unhooked glow plug module.
unhooked engine harness 2 connectors from fuse box
unhooked ficm
unhooked tcm
oil pressure sensor harness is unhooked top and bottom.

under fuse box looks good no cut wires that i can see. I checked the cross wires going from battery to battery. I checked transmission wires for the hell of it.

some pointers of where to go next...
thanks for the help
