Wiring diagram? for Catalytic Temp sensors

My car: a 1992 non-turbo 2-seater hardtop.

While searching this forum did Identify the two probes at the rear of the Catalytic converters as Catalytic temperature sensors, and why they're there.

Searching failed to show a wiring diagram and My Factory service manual (two book set) doesn't seem to have it. The ECCS section, EL section and Schematic fold out does not show them.

I have downloaded 1990, 92,93,96 F.S.M, but they don't seem to show them either.

I don't have problems with the sensors, I just would like wiring diagram for them.

So does anyone have wiring diagram for the catalytic temperature sensors or point me to the page?

 

I expected it to be on the ecu pinout but no dice?

They don't feedback to the ECU. Only to the little light on the dash.

 

Don't have the service manual handy but might be in the EF section.

 

Don't have a diagram for you but they just run into a little box under the centre console/ashtray then up to the cluster.
