Japan Spec 1991 850- the Mid shows a "catalyst overheat" message on startup. I have read that the v12 Japan cars will often do this, and I do know that there are cat temp sensors at the rear of the cats.
I found some stuff about E32's that says to simply pull the relay under the rear seat to omit this feature.
Does anyone know where this relay is in an E31?

K20 is the relay name, as far as I can tell

Rear E-box - IIRC tall yellow one.
