[FIAT PANDA 2004] - Connecting Universal Central Lock: Wiring and Motor Instructions for DIY

I warmly welcome,
Well, I have a problem with connecting the universal central lock in the panda. I must have searched the entire internet and found no solution. The lock is such that they close and open all doors after turning the driver's key. I have equipped the driver lock cassette with the missing motor from which 2 cables come out. And all in all, it is enough for the central operation to connect the control unit to it from the remote control, because it will work as if I turned the key. The motor works in such a way that: Closing - (green cable + 12v and ground on blue) Opening - (green cable ground and blue cable + 12v). For China, I can't get to how to connect it to the switchboard. I will provide a diagram in the attachment.



Best wishes

According to diagram A Bottom left.

I connect yes - white to blue and white with a black stripe to green (signals to open close) yellow and yellow and black should I connect + 12 and ground?

Orange and orange black to the ground, yellow and yellow black to the plus. The other two for the actuator.

tomorrow morning I will let you know if it worked. Thank you very much

In case it closes after pressing open, then reverse the connection of the two to the actuator.

If the entire installation is original, you only add an actuator with 2 wires and it will be controlled by a remote control unit, then you only need to connect this actuator to the control unit, without any connection to the car's electronics - diagram D is correct. You must enter 2 constant pluses and 2 constant masses for the control unit relays, i.e. orange and black orange to ground, yellow and yellow black to plus, the other two to the actuator. The upper relay responds to the closing signal, the lower relay responds to the opening signal. So you normally have 2 masses on the actuator, and depending on whether you close or open, one of them changes to 12V. The actuator resets the original contact in the driver's lock, in response to which the remaining locks close / open with the use of the factory central lock.

? not D but A, I was corrected too.

I can assure you that D ... diagram A is a diagram of internal connections of relays in the control unit, point 2 refers to the described situation, which refers to diagram D, which may not be very happily described as triggering with a plus (but indeed actuator is controlled by a switched plus, and the leaflet was written by Chinese)
The aforementioned control with two pluses is scheme B and it refers to the control of the factory control unit, i.e. there are actuators in all doors and we connect, for example, to the close / open button on the console. In this case, only the control unit for the radio remote control is added and it only sends the closing / opening pulses to the factory lock control unit, and does not directly control any actuator.

However, it is 100% the bottom left one.

IT WORKS !
You are wonderful thank you very much for your help actually a very simple matter ) Best wishes )
