1990 Mercedes 190, Giordon G686TK

Can anyone help me with this alarm:    GIORDON G686TK

Got everything connected (as shown by wiringdiagram) but when alarm is activated the centrallock is unlocked and when alarm is deactivated the doors are locked. When pressing button 1 on the remote the doors should be locked and on button 2 unlocked ,but in our case they work the other way around. The alarm is connected to a mercedes 190 (W201) buildingyear 1990 with pneumatic doorlocksystem.

THANKS FOR HELP!!

Well here I decriscribe the wires for central locking : a plug with 6 wires:   orange, white, yellow, ORANGE / black, WHITE/ black and yellow/black. The car (mercedes 190) has 3 wires: brown, RED / white and blue. According to us the blue cable is the steeringcable for locking unlocking. We connected the wires as shown in the giordon wiringdiagram as follows: orange had to be connected with WHITE/ black, white had to be connected at the pumpside centrallockingwire(blue steeringwire that had to be cut) ,yellow would go to - Ground, ORANGE / black had to go to the driversside blue wire(same wire that was cut before but now the other end), yellow/black is connected to+12Volt. The alarm is connected with a 10 wire plug and is working okay only the centraldoorlock is working the wrong way around so that when alarm is on the doors are open and the other way around. We tried switching the white and ORANGE / black wires at both ends of the cut blue steeringwire of the car but then a fuse on the white wire blows. We tried a lot but without succes. I am very glad with your help!!

Hello everybody, problem solved! At last my supplier provided me with a correct wiringdiagram for my car and now everything is working correctly! Thanks for all the help!!
