I used the black wire from the headlight for ground when connecting a temp sensor and guage. The guage reads real high. About 50 degrees too high. Anyway with the hood open I have run a test wire to other sources of ground that appear to fix my problem. The temp changes to a reasonable number. This leads me to believe the headlight black wire cant be used. I see a black and green coming from the meter assembly that should be ground. Can anyone verify the proper ground under the hood. Thanks guys.
