Question: I ordered a Foxflash OTB adapter, but I don’t know where to find the pinout for OTB?
Here is the clue.
Open the foxflash manager install folder there is a folder called ‘Document’.
The OTB pinout can be found in the document folder.
PDF format in Help folder or check online version via browser.
For example, search CRD3.20 for Mercedes
You will see bench pinout
With OTB adapter, only need to connect GND, VCC, CAN H and CAN L.
Just check his CAN H, CAN L, VCC, GND then back to OBD driver connect with OTB. Don’t need to connect GPT.
If have Kline you also need connect Kline.
Foxflash read and write Mercedes CRD3.x via OTB mode
Connect OBD cable to OTB adapter and add 12v power
Select OBD driver to read and write
