Late model Blue wire with Yellow stripe Dash location?, Where does this wire go? Options

[TINKERGINEERING]

First 3 pics:
This has a small mental female blade connector and goes back to the white cylinder connector behind the firewall.
under the dash near the Gagues, where does this connect to?
Not on the diagram

Last 3 pics of Bezel:
also the two lights on the instrument gauge bezel
I am missing 1 of them but what do they mean and what's the one I am missing?

Basically, what are these and what do I label them?

Thanks! Frances

To answer the questions, what L-Jet914 and Saladin posted gets you there.

The blue/yellow wire attaches to a CAT light on the dash which you are missing. The EGR and CAT lights merely indicated when these items needed servicing.

These are all components of the 1975-76 CA-only model, both 1.8L and 2.0L, that requires an EGR valve and catalytic converter for emissions. The CAT circuitry starts with a sensor to the CAT, and logic box 'relay' at the drivers side tailight area of the chassis harness, not shown in the photos above.

@JeffBowlsby Is the J⁴² labeled as a relay for catalyst temperature control shown in the diagram the logic box 'relay' you mentioned; given the T⁴ connector is labeled as a quadruple cable connector in the rear luggage compartment and the G²⁰ is labeled as the catalyst temperature sensor which I assume is in the catalytic converter?

Yes, exactly.
