Since the Autronic ECU does not have knock control, I bought an KnockLink device.
This device does detect knock through the entire rpm range, showing this by flashing led's. This device does not alter ingnition or someting like that. Just warns.

First I drove with the official knock device from Link systems, but because the box is ugly, and almost nowhere to fit, I removed the leds from the Link board, and installed them into the gauge cluster.
Pretty freaky job, but it can be done, and the result is beautifull. I am very happy with this setup now.

First I disassembled the gauge cluster. Then I took the distance of the led's from the KnockLink box, and drilled holes in the correct size. This is an very tiny job, and needs to be done very very carefully.

From memory the big red led is 0.5 mm exact, and the four other ones are 0.3 mm.

Then I installed the led's into the dashboard, and glued them, so they don't fall off. The led's are having a different polarity. So be sure you connect power and ground the correct way.

Unfortunately the big red led could not be installed right on top of the other four. If I did so, the led should come behind the dashboard, and could not be seen.....

This is the complete build kit. You can see the ugly box. Removing the leds from the circuit board needs to done very carefully, and more care needs to be there when you install the wires on to the circuit board. If the board gets to hot, the board can gets damaged, and that is an expensive solution......

The gauge cluster back in the car again. Here you can see that the big led on top could not be right above the other four leds.
I turned the sensitivity the most sensitiv way, taped the wires, and tie wrapped the whole stuff somewhere behind the dashboard.

And a pic in the dark. Important, because I did not want false dashboard light shining through the leds, making me think of alarm.
If you take a close look you can see the bottom green led burn a little, showing the KnockLink is armed.... :)

With special thanks to mister Klaas Bos (from the Van alles wat store = dutch).
