Hello installation of a radio remote control for your Mazda 626 GE BJ.92 So after a little bit I have got the color coding out now !!! So on the right side of the footroom of the passenger side there is a cover that you loosen and shows up the RELAIS (DOOR LOCK RELAY). From this relay come now 6 cables ZV-AU -> brown with pink bar approx. all 4cm (thin cable) ZV-ZU -> brown-yellow with pink bar approx. all 4cm (thin cable) For the mass on your ZV Control you close the two ground cables of the ZV control (e.g. Waeco, Kings GUN etc.) to the black thick cable on which comes from the relay. Lasting plus you can also pick up there directly on the relay (is the thick green-white cable) Caution: All modifications to your vehicles happen at your own risk !! I do not take any guarantee for any damage that could occur due to improper handling on your vehicle electrics !! price for your vehicle central locking has been tested on the model GE Bj.92. It could be that the color scheme on newer models is different. MfG Tarek
