Temperature Sensor--Which one?

[bdi_fc]

Swapping an S52 into my 89 325is.

The S52 already had a middle hole for the OBDI gauge cluster sensor but it was plugged.

Now, which sensor do I stick in there from the e30?

12- 12621710512
or
13- 13621357414

and I'm assuming the OBDI wiring harness will have a connector for the gauge cluster seperate that will function with the treehouse adapter I have.

Thanks!

Upon further inspection of the harness, I found a connector that matches 13 - 13621357414 one connecting point and all.

So, I'm pretty sure that's it. Let me know if otherwise.

Or is it 16?

I think I grabbed 16 that has one pin within the connector that seems to correspond with a connector on the harness.

The brown/black one is for the cluster, the blue for the ecu
