95 E36 M3 with an 11-button OBC conversion

I have a 95 E36 M3 with an 11-button OBC that has a bunch of dead pixels. I bought an 18-button OBC and a x1071 connector to replace the 11-button OBC. I followed Mon's instructions from these comments to do an minimal install of the 18-button. Finished in 10 mins.

Here is what I did:
1. Move brown ground wire from pin 17 of the x1070 to pin 13 of the x1071
2. Move red/yellow power wire from pin 18 of x1070 to pin 8 of the x1071

Not all of the 18-button features are working because I only moved over the power pins, but at least it's installed and powered on. Seems to do everything that the 11-button used to do. I'll finish up the wiring harness to get all of the 18-button features when I get some time.

Great article and great comments. Thanks.
