Hi,
I am trying to install a GPS/GSM to my Fluence ZE. I would like to be able to control the door lock/unlock commands through an app, but I am having big trouble finding the cables that control the doors. I found two cables that come out of the BCM but they have constant positive current, and a negative pulse is sent when a command is sent. As these cables have constant positive current, I can’t just send a pulse there.
I tried contacting Renault for this, but nobody seems to know
Does somebody know by chance where I can connect and send a positive or negative pulse for opening/closing doors?
Thanks in advance

The cables running to the mechanisms are dumb and provide operating power only.
You need a way to talk to the control module. Do you want to operate the locks from your smart phone?
Interesting - keep us informed
