Fitting OBD2 scoket into volvo 850 OBD1

[t5 pete]

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

That's the right idea, I'd double check everything, is the b block the front or rear section?

[mike 850]

Also what port on the obd connector did you wire b36 to?

OBD2 socket

pin 4 to earth

pin 7 to b36 K-line

Yeah I was going to keep them but the problem is with the little mileage I do it would be years before I run the tread off these tyres on the sats but im in no rush and just as happy if they don't sell.
As for bkv I carnt be doing with that having some one nit pick over my car oooo that bolt is a little mucky lol

I couldn't be ar$ed to clean it that much for bkv and stand around kicking tyres all day to find out I didn't win, rather have me foot flat on the throttle getting smiles per mile.....lol

Following with interest as I need to wire an obd11 for the rear engine.

[t5 pete]

Done some reading and also with info from Chris on voc I now need to wire into B5 as well or try it independently with b 36 removed

[mike 850]

Is it a 4.4 ecu?

[t5 pete]

No its 4.3
