@Steve1975 You don’t say why you are considering replacing the hatch ?.
I can only assume it had become damaged in some way ?.
If so, then sourcing a replacement panel in the correct colour is a great idea.
It has to be a “bolt of bolt on” item surely ?.
Two person job for sure, given the weight of the hatch, that will include the HRW glass.
Oh….. The heating element lines on the inside of the glass, needs protects when handling the hatch, they are easily scratched which will make the HRW useless!.
The wiring loom from the ZS ICE is likely to be different than the ZS EV, but you will be removing it from your car anyway.
I can’t think of any other reason why a ICE hatch would not fit the ZS EV tbh ?.
Yeah - The lake of rear spoiler maybe ?.
But these can sometimes be attached at the factory by the use of strong two sided tape believe it or not.
