Best Method for Connecting OBDII

Post by schaffs7 » Tue May 29, 2018 10:18 am


I have the VW1 and the RR that I am using to install a Kenwood 6904S into a 2009 Audi A3.

My VW1 does not have an adapter to plug into the OBD port as shown in the instruction. From a previous post it seems this may only be included in newer revisions? TH QC check tag on mine indicates that it's quite old.

I would like to avoid splicing directly into the wiring as there has been reports of issues with tuning, and I typically like to avoid permanent modifications if possible.

- Is my best option to create my own adapter (any suggestions on which 3rd party plug to use? Is a Y-splitter a good idea?)
- Should I just return my VW1 and try to get a newer revision? Mine was purchased at a Visions Electronics so they may have old stock?

If making my own adapter It would be great if you had the pins to connect to :D

Thanks in Advance!

If you want to make an adapter, it goes to pins 6 and 14 at the OBD2. (brown/red to pin 6, brown/yellow to pin 14- the green wire is not used).

Otherwise, i recommend a military splice method. See attached.
