In the LS info sticky is a sensor location thread with pictures labeled and whats needed. Direct link https://www.trifive.com/forums/showthread.php?p=517784#post517784

I agree with Hotdog installer is iffy. I would keep the MAF sensor, your get better driveablity and MPG. Most installers delete it as they are to lazy during install. GM used it on Millions of vehicles so why not keep it.




To add CC to Gen III DBW which is pictured you will need to add a CC stalk that will work with the GM TAC (throttle control box) Depending on who did the harness you may have the wires out of the TAC box already all you do is simply hook to the CC stalk, brake light correct switch, and that's pretty much it.

My installer is OK with the hookup of all sensors noted, but to be honest I don't feel safe with anything except factory installed cruise control.
I do want my computer savvy engine to work at optimum so I will stress for proper hookup of all sensors necessary.
Thanks,

Who is doing the engine harness?? The engine harness, if its a reworked stock GM LS harness, will come with wires for the CC stalk. Most places that rework harness will provided the wires already for CC and your year motors. If its a store bought unit then who knows ready the instructions.

If you paying this guy to do the install he should know what to do and not have the owner asking questions to figure out stuff that is common knowledge for swap shops.

Based on would you just stated the guy obviously doesn’t know LS motors. Nothing wrong with that but hard to pay someone money and not get what you pay for. If it was me I would cut your losses take car running and driving. Then go to an actual shop that does LS motors. They can tune inhouse most times, add MAF, and at the CC etc. They would dyno tune and dial everything in. Its seems your doing that anyway so why waste money on were it is especially of guy has no clue what he is doing to have to fine a “geek” to tune it.

I can do that if someone is willing to recommend a shop in the San Diego/Los Angeles area, because there is no such shop that I know of in a 100 mile radius of where these cars are being restored.
I contracted this fab shop to remove the old engine, cut the front clip, restore the old floor pan and install a custom made front clip, and mount the 2004 5.3 LS with a 4L60e transmission with a guarantee that it ran. He also installed a new radiator, rack and pinion steering, Willwood brakes, Lokar shifter, Sanderson Headers, Flaming River steering column.
Just recently I asked him to install the Dakota cluster panel, and the Painless wire harness to install the lights. Then he's done. Before it goes to paint, I want to see this puppy run like it should, but I'm not expecting him to accomplish that.
I hope this explains my situation a little better.

Yes that explains it.

Get it running driving and working. Then you can take to a tuner to dial it in etc that will help. The CC is easy to add later for most part as mentioned here so don't worry to much about it.
