I want to do the same thing as you, a swap from QT1 to QT2. I own a 11' JGC Laredo with QT1, I already have the T case, knob, and module from a 12' JGC, according to the wiring diagrams that is all you need, the only missing information I need to start the swap is the CAN BUS programming, I have not found if the TIPM would recognice the data, if I need to reprogram or another TIPM model.
If I figure something else, I would post it.
I'd be shocked if you don't need several drive shafts as well.... ...the electronics often have to be configured, i.e. they may have the same TIPM, but electronic boxes in the TIPM software need to be checked off with the electronic tools to make it work with QTII modules.....
Also, modules are given part numbers by software loaded into them, all the PCM's for the WK2 are physically identical, but they have different part numbers because they have different software loaded in them to control the different versions of the WK2....
The biggest risk I see, is that you'll need to configure the electronics.... ....so you go to the dealer and have them configure the electronics with their tools, and they'll come back and tell you it can't be done.....
They have idiot proofed the Dealer tools so much, to prevent tech mistakes, it often turns out that anything that is not the standard pre-planned servicing, is not allowed and can't be done....
Part numbers are big in this, even if the PCM is physically identical, just needs the software for the other version of PCM loaded in it, the Dealer tools are idiot proofed and won't allow the tech to load software for the wrong part number module....
A Brit imported his British Export Jeep Commander with him when he moved to Canada. The PCM failed and he got a new one, needed the VIN# written to the PCM to enable the immobilizer, otherwise the vehicle would not start. The Canadian Dealership couldn't do it, there tool said this is a British Jeep, they're not allowed to work on it with the Canadian tools.... .....The Dealer and Owner contacted Chrysler Corporate several times with different solutions to how this could be fixed, just let the Dealer use a copy of British Software for a day, etc.... Chrysler refused, the only answer they would give the Dealer and Customer, they would have to ship the Jeep back to Britain to be Serviced....
So you may be stuck with scrounging up more parts, like the TIPM from that vehicle that is already configured for the TIPM, or getting the very expensive third party, reverse engineered electronic tools that aren't idiot proofed like the Dealer tools.....
