04 Yukon Denali AWD to 4WD swap

[EfiniMotorsport]

I've got a few questions about swapping the AWD transfer case in my 04 Yukon Denali to a push button 4wd setup and wanted to know if anyone's done it. I talked to transfer case express and they said to use a 263 case as it is dimensionally the same so I won't have to change drive shafts. I will also be doing their case upgrade to prevent the oil pump wear issue. I know I need to swap the right side of the front axle so I have the diconnect as well as add the switches, transfer case control module and associated wiring. I have a parts truck I can pull everything I need. What I'd like to know is how much wiring goes somewhere else besides the switches, controller, axle and transfer case. I'm hoping it only connects to the fuse block and doesn't run into any other modules. I also need to know if I need to get the ECM or BCM reprogrammed and if the VSS is the same on both cases. Anything else I may be missing? I've only found one person to document the swap and that was about 6 years ago. I've also seen people swapping 4wd to AWD but that was mainly for traction at the track. I'm looking for better mileage.

In case anyone looking to do this swap stumbles across this post I'll cross post this here too. I've been researching this swap for probably two months or more using every combination of search words I could think of. Today I happened to swipe on my phone and look through the news articles and found this article on pretty much the exact swap. Sometimes big brother can be helpful I guess.

Here I am reviving an old thread but I am currently looking to do the same swap on my 03 Denali XL... did you ever successfully complete the swap? please let me know!

No I didn't. And unfortunately my built transmission ran low on fluid and burnt the clutches so I'm parting it out

Where do you have the vehicle listed to part out? I need some parts
