I want to ask if anyone here have wiring diagram of parktronic switch becouse I cant figure out how it works. By the way, I am trying to get OEM switch and aftermarket sensors to work together.
So I just want to know what these 12 pins are for???
Any help???
. . . and some aftermarket parking sensors. Now I want to retrofit them as original as I can.
First obvious problem:
. . .yes, this "switch" is more complicated then Nokia 3310.
Lets concentrate on right side of board. There are 12 pins witch connects to parktronic control unit. Since I dont have PCU I need just one toggle switch and my sensors are good to go. I need yellow and red LEDs to work as well . . .
I am struggling with this two days now. Only thing I discovered is that pin 1 is + of board and pin 6 is - of yellow LEDs. Then I figured out something . . . I know its not professional, but hey, as long as it gets job done . . .
Green/white wires on the left are + and - from yellow LEDs. I will hook them to P R N D module LEDs. That way I can control them with dashboard dimmer. Everything will look original.
Two white wires in the middle are two sides of push button. This will be used as signal to releys that will work as toggle switches. First will be placed in trunk for rear sensors, second under the hood for front sensors and third will be somewhere around shifter, he is there just to toggle red LED . . .
Finally, orange/white wires on the right are just + and - of red LED. I have soldered them directly to the LED. Everything is SMD so this was very tricky.
I hope I will catch some time next week to finish this little project.
I will post everything here.
If you ask me why I didnt bought full parktronic . . . I have paid 10euros for the switch and 20 for both rear and front sensors, so it was kinda bargain.
