OBD Cable Wiring

[javars]

Hi
Have just installed fes to turn out engine light after cleaning my egr.
I am going to modify the cable as per the website
"NOTE: You have to solder a short wire between pins 1-7-9 of your interface's OBD connector in order to connect to ABS and Power steering ECUs. Also, you need to have a connection on pin 3 of the OBD connector in order to connect to airbags"
So, do I solder all 4 connectors together ? Or just the 3 which I have done in the attachment
Any help / advice would be welcome
Thanks
Steve

It is NOT recommended to connect 1-3-7-9 together.

As you noticed Pin 3 is for the Air Bags. It is always advisable to ONLY connect ONE electrical connection to the Air Bag System.

Pin 7 is the KKL interface line.

So your connections should be Pin 7 to Pins 7,1 and 9

AND

Pin 7 to Pin 3 ONLY.

I think its is better to invest in a dedicated cable conection set (as sold by gendan.co.uk) or to use an OBDII Patch/Breakout Box.
