Only the factory one's for each harness not a guide as such.
Quite involved. If I was to do it I'd want a harness from each. Mainly for extra plugs snd routing.
Not impossible just time consuming. Factory diagrams are in the wiring section.

What's the need for the buick in the VU? Speedway?

Id find another tuner. The MAFis not a restriction. There's a thread on here with someone making a VT to VY patch loom.
Lots of hour's it would cost you a few hundred. You could possibly run the ecotec straight off a VR harness?
The VU ecu is tuneable with the MAF.
