I've been asked to possibly fit a obd2 socket into the gul for live date readings after doing a little searching there a bit on info on the net and all point to 3 wires one for earth one for live and the other to b36 K-line to the ecu.
So today I started to fit it but did notice that the K-line wire from the obd2 socket actually splits into 5 wires.


Wire run for pin b36
But as it said it only needs to go to pin b36 that's all ive done once wired in I put the reader on but it just keeps up with no coms weather ignition is on red or weather the car is running its just the same.
Am I missing some thing as to me with that white wire splitting into 5 would they all need to be connected to their correct places to read date?
Any help of info would be much appreciated
