Temp Gauge Wiring
I am installing an aftermarket temp gauge, etc in my 68 -- it only had the idiot light. My question has to do with the existing wiring, and I'm going crazy trying to deal with the wiring diagram. Searched the forum but have not found an answer. The diagram(s) show a green wire from the sensor to the instrument panel plug, and a green wire from the ignition switch (the "GD" terminal) to the same terminal on the instrument panel plug. I have installed the new temp sensor in the engine block, and cut the green wire coming from the sensor to the instrument panel plug and connected it to the new gauge.
I think the green wire from the ignition switch is a momentary ground to test the temp idiot light when in the start position? If so can/should I disconnect that wire from the panel plug?
Also, what's the best way to get 12 v "accessory" power to the gauge cluster?
