You need the C1 and all its wires connected into your harness, plus you'll need the Vehicle Anti Theft turned off and a tune added into ECU.
You'll probably want an OBD2 port added to the harness.
There will be parts of your GTO harness which just wont have anywhere to plug into your Jeep.
Seriously I'd consider boxing up the ECU & harness and sending it to a professional to get everything done for you and to suit your Jeep.
(One major reason here is your location.....parts and support for this equipment will be scarce there where you are.)
