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.

Thankyou. That makes sense now

the presentation method is very good because first they explain the intitial things and secong phase it is start to describe the main things whick is necessary to explain it.
