I bought a z06 corvette and it seems to have RPM issues with the main culprit believed to be the wiring harness according to the dealer. They found some voltage issues at connection x106 and believe if the wiring harness is replaced, then that will resolve my issues.
The part number I need is 84069441 however it's on national back order with no estimate of being in stock..
What are the options I have to get the wiring harness I need OR sourcing the proper parts that I need to repair the harness?

Most often when there are issues with harnesses, it's chaffing, broken wires at the pins, or broken connectors (ie someone broke the locking tab and now the halves don't stay together).
If you really want a different harness, then it's time to shop the salvage yards and eBay. Facebook Marketplace is another one to check. Do keep in mind that the guys parting the cars out have a pretty good read on what's no longer available and will often charge an arm and a leg.
To me, the best option is to repair it. I'd examine as much of it as possible while it's in the car for breaks or shorting due to chaffing and I'd inspect the connectors for proper seating. If it all looks good, then remove it and check it again. Keep in mind that with a simple meter you can do end-to-end continuity checks of each wire.
Almost without fail, all the connectors are available through a place like Mouser https://www.mouser.com/c/connectors/...ve-connectors/ The connectors will have part numbers on them, it just takes some investigative skills to look up the brand and specific parts....the shells, insulators, pins, CPAs, etc.
I'd ask the dealer what pins they're seeing these abnormal readings across. If it's a couple wires.....just fix the harness.
I honestly hate scouring for parts which is why we dumped the modified C4 for the C7 and plan to dump the C7 once it starts on that decline. The question is whether you need it now or not. If you don't, why not wait till spring? At which time you can have it fixed.

If the part is not available right now, you do not have many options other than a salvage yard, someone parting out their car, or just fixing the one already in the car. I would probably look at the latter option if you can narrow down where the problem lies.
Curious have you done a google search your self not just relying on what dealer said . Only reason I mentioned this is because a few years back I needed a part that dealer and a Corvette shop said was unavailable nationwide and 15 minutes later on Google I found a place that had three NOS gm parts in stock bought part and had it shipped to shop arrived the following morning . Shop could not believe I found one . So might be worth searching . My thought was dealer just went thru there normal connection were part was on back order and my search was a much wider search . So might be worth some searching. Before you purchase might check to make sure dealer will install part you bought if not maybe you can give them info on place that has the part and they can purchase part and install.i did a quick search for your part and some show up but not sure if info is up to date. Good luck !
Update the place I bought part from was SMC Preformance auto parts they specialize in Corvette and Caddy XLR parts . There in Michigan and were great to buy from helpful and shipped over night . This was back in around 2014 part was for a C5

Therein lies a problem. If the part they install doesn't fix the problem or has one of it's own, who owns it? Usually when a mechanic, dealer or not installs a part I provide, it is "No Warranty". If my tech buys a set of pads and rotors from say Autozone and it fails, they can claim labor and parts and it won't cost me a dime. OTOH, if you bring the part, all they warranty it for is their labor. If they blame the part for a problem, you are on your own. I really, under these circumstances, would prefer not to have them install a part I provide. I would rather they go get it themselves and warranty it.
The problem is more than likely in the connector. Fixing the connector could be difficult due to where it is located. In addition to purchasing the connector, you may need to purchase the tools used to push connector pins out of the connector and into a new connector. Remember, X106 is a connector half that is part of a harness. There is other half of the connector is on another harness or module. Either one of the connector halves could be an issue. I don't know which half (male/female) the dealer is proposing changing. To repair/replace the connector you may need to remove the harness anyway, then the choice of whether to replace or repair becomes moot since labor and parts charges to repair are likely higher than labor and parts cost to replace.
If you can access the connector and disconnect it spraying the contacts in both halves of the connector with electrical parts cleaner and connecting/disconnecting/connecting the connector 4 or 5 times may resolve the problem. The multiple connections help clean residue from the pins.
