Own a 1976 280z stock. I recently received a very generous Christmas gift of full Intellitronix gauges for the Z (Speedo, Tach, Fuel, WTemp, Oil press). I am trying to delete the clock and voltage meter. Each gauge comes with 4 wires (Power, Ground, Signal, Highlight Dim)
I have installed the Fuel, Wtemp and oil pressure gauge in the appropriate location by cutting the connector off the stock gauge, splicing and taping into the connector with the new gauge and then plugging it into the stock harness via the stock connector. I was able to get a image and reading from all three gauges. I then decided it was time to move along to the speedo and tach. As soon as I removed the tach/speedo I have lost all power to my 3 smaller gauges. I attempted to reinstall them but realized I had already "hacked" into the tach with the new tachometer so its not possible for me to recreate a stock tach setup. I don't seem to understand why this is happening, checked all fuses as well. Is it a better idea for me to wire all the gauges off 1 power, 1 grnd, 5 individual signal wires, and 1 headlight dim wire?
I apologize if this is vague, electrical work is daunting. Thanks for any input!
