Good day. I was given the task to connect a lock control unit with two remote controls in Citroen I C2, in which the central locking is already controlled by a key. Most of the topics concern C3 but in C2 BSI it is apparently the same. I found the diagram for the Car protect bx40 control panel. I have a Motokey 500 switchboard. I will briefly present the BX40 connection Unfortunately, the motokey switch has other connections, which is why I have a problem with connecting.
If anyone can help, then he can figure out how to connect the wires.
And in BX40 and motokey 500 is connected to the plus control only that in BX40 shorted to plus you have yellow and yellow-black and in motokey500 connect to the plus yellow-black and blue. They only differ in colors. The rest as in the diagrams, compare BX40 Z 500 plus control and connect.
Citroen C2 plugs, cube No. 2 is the black one on the back. You attach the turn signals to it. Cube No. 3 alarm supply + 12v permanent independent. Weight attached to the body. Cube No. 1 controlling the central lock. You cut the cable No. 13 and No. 15 and connect as I wrote.

One end to the car's weight, the other to the ankle pin. turn the lock if it lights up you have + 12v control. I had to increase the locking time from 0.5s to 3.5s. By removing the jumper.
