P38 Steering Wheel Controls

[QUOTE = "Doo, postagem: 4492576, membro: 130183"]

Hello Doo, Did you make the call? i'm trying on my radio, but i can't. my P38 had no controls on the sticky, so I bought it on the scrap car iron. 7 wires come out of the steering wheel, 3 of them are purple / black and are welded together. What wire did you use to connect to (Key 1)? Was it yellow / black? under the steering wheel I have a second connector that receives the wires from the steering wheel and changes the colors. I've seen wue the purple / black has to be the GND, now I can't find the other .. can you help me?,
