Technical Wires harness cable rear trunk

[Divo]

Regarding GP T-jet 2009

I need to replace the wires that goes through the cable throughput the one aside the hinges of the reardoor. (see pic)
Ofcourse I simply can connect some new wires as repair but I like to know the function of all, just in case something is not working right.
Does anyone has an electrical scheme? I couldn't find. In mine I count 11 wires + wiper water line

Are there more functions involved than these 4?
- Rear-screen wiper
- Third brake-light
- Boot lock
- Rear window heating

Hello,

Here's a link to online eLearn module to the Grande Punto electrics / electronics:

Home Page

aftersales.fiat.com

You should be able to find all the needed information. And much more

Thanks, I already looked to possible info on sources like that but its total rubbish those schemes.
The info I'm looking for is not there, or I overlook something. . . .
I cant find a description what all the wires in the bundle are by color and function.

This is a Fiat style of providing diagrams/schematics. Yes, it is dumb.
They split almost everything by function (so I guess there's no "front right door diagram" for example - it's separated into: mirror, locking, windows, speakers and so on). Or there can be "full diagram" if the panel has separate, dedicated connector (plug/socket). If not, like boot/trunk door, it's shattered into multiple functions.

But you can still do "reverse engineering" using those bits of information. Track ("ping") wires to the pins in the Body Computer and fuse boxes etc.

Some functions like that have feedback (limit switches for example), so it's not actuator (motor) only. There will be more wires involved.
Then, add some doubled powers and/or multiple grounds to the mix. Therefore "4 functions" require way more wires than 4.

In the "boot opening" section, you can click on the actual part (N057) in the table below picture. Lock motor. It has a plug. There are colors coded (abbreviations) and cross-section (is it thick or thin wire).
