notyepcars 10 Report post Posted August 14, 2021 Does anyone have a cluster pin out that would show where each pin goes. My car has a tach, and the wiring diagrams I have purchased do not show this. Top and bottom pins on each side are not used, pins 1,9 and 10 and 18. The other 14 have wires going to them. I really need to know which numbers are grounds, and where they are grounded. Any help would be great. Thanks Quote Share this post Link to post Share on other sites

Brian Conway 264 Report post Posted August 16, 2021 Thank you. Reading the panel at my home is a bunch easier and makes more sense. Got another trivia question ? Two unused/vacant connectors at the firewall ? Auto shifter illumination and the other is AC compressor ? Which is which or something else entirely ?

Midlife 814 Report post Posted August 16, 2021 Green wire is definitely AC compressor lead. Brown wire is PRNDL lamp lead. On a 70, there is an additional white female plug which is RUN-only for the carb anti-stall device. Quote Share this post Link to post Share on other sites
