If everything else works, you don't need it!
Maybe something for cruise control?? My FSM doesn't go back that far.

| Post subject: | What are these wires for |
I am currently giving my D100 the HEI ignition upgrade and cleaning up the 50 years of hacked wiring under the hood. I do not have a 1975 specific service manual or wiring diagram but have figured out almost everything I need to remove/change/replace in order to perform the upgrade. I am stuck at this connector going into a cover on the speedometer cable. It is not listed on my wiring diagram. https://photos.app.goo.gl/sbw3Wbq3durokW1n6 The yellow wire goes to another connector that has never been connected to anything since I have owned the truck. And the dark green wires went to the Electronic ignition. https://photos.app.goo.gl/iYPxzoRmQQnBjy3P9 What is it? Do I need it? And if I need it, where does it get connected? Thanks in advance Dennis |

Just a wild guess, without looking up anything. The timer/counter for the check emissions light. Not sure if that was a feature on that year/model. |

Thanks for the responses. The emissions counter make sense. The engine has been replaced. Which explains some of the wiring nightmare. Plus 50 year old wire can be pretty brittle. Dennis |
