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 Attached thumbnail(s)

Catalytic converter temperature warning light and EGR reminder light. The 4 pin connector goes to the EGR/Cat timer box.

@TINKERGINEERING hopefully the below service manual current flow drawings clarify the connections.

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.

Thanks for these print outs I am printing and saving. I want to get the CAT bezel light button just to have it there. may need to add some other meaning to it eventually. Hey thanks for all the responses and so fast. 914World is amazing |

EGR - Energy Gone, Recharge (low watts)
CAT - Charging Amongst Teslas (charge in process) (IMG:style_emoticons/default/biggrin.gif) In case you didn't know, Tesla Superchargers is the only network that's populous, reliable and constantly maintained enough to make EV practical. The others are essentially a bad gamble. |

The previous DC build guy removed all combustion bits.. Apearently including this sensor module. now the plug makes sense thanks for the great pic. Frances Dad gave a thumbs up too (IMG:style_emoticons/default/bye1.gif) |

I was on youtube wanting to see where you are at on your project but only came across a 1 year old video of a news reel. Any newer videos? Your getting closer to getting your license?

I wired the cat light to my oil cooler fan. The light comes on when the fan is running.
