Couple of wiring questions re: my LS swap

[Chevydillan]

First off does anybody have a diagram for the TAC module? There are 3 wires that were in a body plug off the donor truck and 1 that was I. The fuse block that I'm not sure what they are.
Second where should I tap to get power to the pink wire for the MAF and TAC ?

2 of many questions to come I'm sure. Thanks

Oh, 04 5.3 going in 97 rcsb 2wd auto.

Good thanks.
Now where's a good place to get power for the MAF and TAC?

Those r usually powered at the fuse block. So just fuse them to a 12volt source. Maybe shared off another source for other sensors.

[Chevydillan]

I was thinking about sharing from another sensor. So that's ok then? Like maybe an injector pink wire or really just any pink wire?
Also what about grounds to sensors like MAF, can I just ground them to the engine or do they need to be grounded through the computer?

That should work the only problem is when it comes time for any future trouble shooting you will have multiple grounds, as well as ignitions(pink)So to avoid yourself any future headachs I would recommend running all grounds to the same location, and try to keep the splicing for your ignition (pink wires) to a minimum. Less points of failure equals easier trouble shooting.
