I have a 2008 crew cab WT and a donor 2008 crew cab SLE I'd like all the SLE features and want to know what modules I'll need to swap without getting my BCM reprogrammed. My dealer won't do it for me. So Im ready to change all necessary modules in my truck with the donor truck including the ignition. Can you tell me if this is possible and what I'll need to do and what modules to replace? I understand they go by VIN or something. But if I get all the stuff from the donor and move it over to mine it should work without locking me out of the truck right?

I don't think there's a single thing on these trucks now that you can just simply "swap out". Just a replacement door window switch requires BCM programming from '07 onward.

You could probably get the steering wheel controls for radio, Bluetooth, mirrors(if they are different), middle seat/arm rest, drivers information centre, fog lights incl headlight switch and harness from lights back to fuse box, and you could take a look at instrument cluster to see if it will simply plug in and work or if you can just replace parts of it to add in the two missing gauges. 

Any other "options" require a lot of work and bcm programming. Options like the dual zone HVAC require extensive changes. 

I would be interested in hearing about adding the two gauges to the existing 2 gauge cluster.

If I get the BCM and use efi live to change the VIN but not the programming to match my VIN would that work? So I have all the features available from the donor bcm? Because in EFI live you can rewrite Vin numbers on any module without flashing them. It's just an edit.

Don't think the BCM works that way. The suggestions I gave do not require BCM programming and are typically simple swaps/installs.  I know this because they were the first things I did.  I bought a leather wrap steering wheel from GM to get the radio controls.

I feel like doing a cab swap or engine trans swap might be my only option then.

You don't say what condition the donor vehicle is in.  Perhaps the way to go is to fix the donor with parts from your WT.  If it is collision damage, it may be better to simply move body parts.  You will need access to a large enough area to protect both vehicles during the change over.

Having gone down this road before in the days when these things were easy,  I'd cut my losses and just buy another one that has all the features you want. Sell what you've got for parts, or as a package, to recoup some cash. Remember, there are ALWAYS unexpected expenses / problems when tackling a project like this ... and that's WITHOUT modules or computers!

 

You'll thank me later. Trust me on that one. Much less stress! It ain't worth it for something you'll barely get 10 years out of anyway, and will probably be a constant headache of electrical gremlins.

 

If it were a '95 or prior, it would be worth the effort ... but not today. Just my .02.

My truck has a 6.0 and fully built trans and regeared to 456 gears front and back and low kms. The donor truck has 520,000km good body but everything in the drive train is shot.

You have an HD truck.  Donor truck must also be an HD truck.  Assuming it too is a 6.0 your easiest swap is to take everything attached to the frame from your truck and move it to the donor truck.  With both trucks having same driveline use the best of both vehicles, leaving wiring harnesses where they are.  The ECM should stay with the truck, the transmission has the TCM inside, leave it in your transmission when you move it with engine over to old truck.  Use the best suspension parts, likely the stuff from your truck. 

It's still a lot of work, but it is what I call easy work. 

Your ECM has been tuned to support the gears hasn't it?  You could take your ECM, just need to relearn security procedure.

    • Yes. You need to check out that thing, and the hub further.
    • Would this be normal or a worn CV Shaft? 51K miles 3.5" lift? Boots are intact and no visible leaks showing. Attached is a the video I took. Thanks     https://youtu.be/ZnW7PPRmjJY?feature=shared    
    • If everything checks out at the MAF, then the MAF is BAD, new or not.   You don't need a signal generator to troubleshoot this. PCM needs ALL powers and ALL grounds able to light a halogen headlight bulb - if it can light the bulb bright, then the wiring is good enough to run the PCM.   Best thing you can do for yourself is spend some time here: scannerdanner.com - Check out all his YouTube videos on similar issues. If you decide to subscribe it's the best bang-for-buck ratio in the automotive world, hands-down. He's got TONS of free vids on YouTube, too.
    • Yes, I used my multimeter to probe all of the wires at the MAF, both with the sensor connected, sensor disconnected, key on engine off, key on engine running, etc etc etc. I probed all of the wires again at the PCM, at the connectors, etc. All voltages are what they should be according to the service manual/wiring diagrams. All grounds are good, less than 20 millivolts from the battery negative under load. Both at the connector of the MAF, at the PCM connector etc.      I know this throws a pretty big wrench into things, but this truck was acting up before the swap. I don't have very much information, if any on what was causing it, but if you cleared all of the dtcs it would do the same thing where it would crank, fire, then die. And it would do the same thing a dozen or so times, and eventually it would start and run, but the difference is that it would run and actually be drivable. Whereas now if you can drive it at all, it goes into reduced power mode almost immediately, and even then it's not running correctly. When you come to a stop at a light it stumbles down to for 500 RPM before catching itself and returning to the smooth idle. And if you go more than about 50% throttle then it immediately goes back to doing the misfire thing.    Like I said, I know that throws a wrench into things, and unfortunately I was not able to pull any data or anything like that before I did this work, so I don't have much to go on.    I'm trying to not fixate on one particular thing as the cause of the problem, but it seems like all avenues are pointing me towards the PCM. Like I said I have tested the wiring extensively (see above), and during cranking the sensor does produce seemingly legitimate values at least according to my multimeter, but as soon as the engine fires those values quickly descend into gibberish. I've tried it with multiple different known working sensors, I have done literally every test I can think of multiple times on the wiring (probing the signals, probing the pins with the sensors unplugged, probing the pins at the PCM, voltage drop, voltage drop under load, continuity, ohms, and double-checking everything against the wiring diagrams/ proper values in the service data.)    Another thing that pushes me towards a possible PCM failure is, I have noticed in troubleshooting a little bit taking a break and coming back, that when I leave the truck to sit for a while and cool off, it starts and runs smoothly when I first start it up. However once it warms up. It starts having problems. For example, when I went out to the truck this morning after it had been sitting overnight, I was actually able to drive it down the block. And then once I got on the throttle a Little bit after going about a thousand ft, it started misfiring again. I pulled it back into the driveway, shut it down, and started it back up. It idled smoothly. As soon as I touched the throttle it did the misfire thing again. From then on as soon as I started it it would misfire. I shut the truck off and went to go get a coffee and do a bit more research. When I came back out I started the truck up and it immediately went into the smooth idle. After a couple of minutes of playing around with it, it would not idle smoothly anymore. Let it sit a couple of hours, rinse and repeat. This makes me think with temperature change something is going wrong inside the PCM. I have the PCM out of the 2007 donor vehicle and I'm thinking of getting a one-day subscription to the ACDelco programming service to try and program that and see if it helps.   Like I said, I'm really trying to not fixate myself on one potential cause, but it seems everything is pointing me towards PCM failure. I would really like to try to confirm that, but unfortunately I don't have an oscilloscope or a signal generator to do the GM service procedure where you feed 5 khz into the signal pin.
