How to connect CGDI MB to w164 EIS on bench

Looking for the wiring diagram that CGDI Prog MB connects to w164 EIS on bench? read this post.

Question:

my cgdi mb can’t connect to w164 EIS on bench – I have got gateway emulator but need to make proper cable for it, could You help me with wiring diagram ? – I know that aliexpress has got nice kit of cables but can’t wait a month or so for delivery.

btw.
I have got XHORSE Power ADAPTER with direct cable for W164, but it doesn’t work with CGDI – I noticed that this adapter doesn’t allow to pass power and data when connected between cgdi and w164 EIS, seems to be useless for CGDI owners for now. That’s why I decided to connect ordinary gateway emulator but need connection diagram to build a cable.
