Is the harness in the oil pan? If not, your post is in the wrong forum.

No it's not! Harnesses are EXTERNAL TO THE ENGINE! Get a life...

Its going to be the same... If your keeping a 4l80 trans... You'll need those connectors. Off hand I'm not certain... But the range gear and other sensors might be same as the 4l60 connectors. Grab your dikes and go to the junkyard. Harness/pcm wise... Its a blue n green pcm and harness either way. But 1 think I would do going into an older vehicle... Get the harness. Oil#switch is going to be different but you can swap switch out. Redo the harness and get a 0411 ecu. Dbc tb type. Get vats delete. If you want to use an older auto trans or stick , have it reprogramed for such. Not sure if you're familiar with all that side of the swaps. Either way.. Get vats deleted.
