Wiring in 14point7 wideband

[E30_Beau]

I need help with my 14point7 wideband sensor because im not getting a reading on tuner studio with my MSPNP2

The wiring on the harness side is;

Blue/ Green (12v power)
Brown (electrical earth)
Brown (earth)
Black (Signal)

Also i have 2 Brown earth wires and in all the diagrams i have seen i should have a yellow but do not?

And wideband side

Red ( power)
Black ( electrical earth)
White ( earth)
Green ( linear output)
Brown ( simulated narrowband output)
Blue ( Temp LED)

Now i have wired it in the following

BL/GN --- RD
BR --- BK
BR --- WT
BK --- GN

Have you confirmed you are getting a 0-5V signal on the green linear output?

If so, have you calibrated your AFR table in tunerstudio?
