I have a question about my 2016 Express and upgrading the uconnect to the 8.4 model. Currently I have the 5” screen radio, but recently found and purchased a new single zone digital climate control bezel with a VP4 radio and am ready to install.

My question is about the wiring harness. Most videos and write-ups explain when doing the upgrade, you’d be going from a tradesman 4-5 speed fan to a 7 speed. Hence why you buy the harness and the new climate control module for it.

But with my current setup, I already have a 7 speed fan. So do I still need the new wiring harness and climate control module by the passenger door? Or will everything just plug and play the way it is?

Thanks!

Am I going to need anything else to make this work…I don’t have an alpha OBD2 for truck setting tweaks. I know I’ll need to contact Sirius XM to transfer my subscription over…maybe the radio needs an update?

@Mpgrimm2 can make you the harness you will need and let you know what parts you mY still need based on your truck and the parts you already have.

Yes. At a minimum you will need the 8.4 conversion harness and HVAC module... Whether you need anything else depends on your exact truck setup/features & the actual year & PN radio you're using.

Send me a message if you'd like to get additional details for purchasing a harness set, etc and I'll be glad to get to squared away.
