Sorry. English translate.

Could you add photos with relay + diode part pcb? Thanks.

Have only pictures from previous setup. But is very similar to actual setup.

Thanks!

i can't understand relay platine scheme and can't see solder  at photos. I found same relays at eBay. Could you add simple scheme using that sip-1a12?

I see at scheme that 2 relays have pins 1 and 3, a5 and 6 all conected, but photo shows one relay inverted or without logo (?)

Doesn't matter how to connect relay.

Example:


Pin #1 and #7 will be closed if 12V and GND is on #3 and #5 (or #5 and #3).

How you connect 12V and GND to pin #3 and 5 doesn't matter. Only make sure the diode is connected like this:

Anode is connected to GND pin (#3 or 5) from relay
Cathode is connected to 12V pin (#5 or 3) from relay

How this diode work and need to be connected, you can see here as well:
https://en.wikipedia.org/wiki/Flyback_diode

Are 1a-12v relay and small diodes enough? I'll use with >40°C sometimes.

Could i install without retire whole door panel?

A simple Diode 1N4148 or similar is enough. No need special stuff.
The relay did not switch the motor it "simulate" a simple switch, that switch +12V as "Up/down" for the PSA box.
Because Renault/Dacia switch the GND signal and not +12V.


You can cut the cables without removing door panel, but you have very small space for it.
But I am not sure if there is enough space below the switches for that box with cables...

I have dokker, with smaller button panel. I´ll try to do it.

Thanks and sorry again for use english translation!!

Could we make plug and play adapter using nissan audio adapter? Seems similar...

no idea. find it out 

Nissan stuff often fit on Renault and Dacia - same company...

prototype. Nissan connectors plug&play. Working!!
