Help fitting hks afr

Hi guys.

I'm after a little guidance.
I'm fitting an hks afr.

Pin 36 i can use for the live?
Pin 39 i can use for ground?

It tells me Conect the yellow afr wire to the wire going to the ecu.
And Conect the white afr wire to the wire going from the ecu.

Pin 16 is the afr wire.

Is that in or out of the ecu?
Also if it is in, which pin is the afr out?
Or if it is out, which pin is the afr in?

Also when I cut the afr signal wire and put the hks afr in its place, will the ecu then throw up a fault code because it's no longer getting a signal.
Or do I just splice the ecu wires so the ecu still gets a signal?

Okay. I have figured it out I think.
Can someone just confirm this please.
(ECU MAF signal wire) Cut the Orange wire in half this is the MAF signal wire that will be running through the HKS AFR.
Yellow wire to Orange wire connect to ECU.
White wire to Orange wire connect to MAF.

Cut pin 16 wire so you now got 2 ends
The end that goes to ecu has the yellow wire connected to it
The other end that feeds back to Maf has the white wire connected to it

Ecu still gets a signal (just a trimmed one via afr unit) so no fault if all wired & working correct


EDIT
you got it stu ...

Thanks MrB

which one you got stu, is it the single adjustment dial one with 4 wires !?

Yes mate. Just the basic one.
The car had one installed when I first bought the car in 2009.
Ot no longer there and I just want to raise the afr slightly so have purchased one
