Not able to get the device to work #29

Hello, I am at a loss, I have had this working in the past, I do not know what I am missing.

At the moment I have just the clock busy and data lines connected through 100R resistors to get the HU to recognise it. I am powering the Nano from my laptop, I seem to remember it used to draw power from the HU directly, but this is not happening.

Can you confirm the connector shown in the diagram, is this pinout looking at the female side on the HU?

From the serial debug I just get 'conn' every so often.

Hope you can shed some light on this. Thanks in advance!

Nevermind, I did not connect ground, my fault.
