Wiring advice

[JERRYCO]

Hi. Can anyone help? I’m wiring up the heated rear window and central locking, on a Ford Ranger 2019 Hardtop. And I can’t find the colour code for either. I believe the heater comes from the wiring loom under the bonnet, but don’t know were, and I can see the loom going into the tailgate but again don’t know which colour. Thanks
