Wiring question for temp sensor.
See pic. Left side is the sending unit wires,black and blue. The middle shows the connector that came with the vintage gauge set. Note the middle pin is not used. On the right is the RF dash harness connector. Note the left pin is not used but the middle one is used.
Assuming I am supposed to connect the RF dash harness directly to the gauges, does it matter if the signal is on the left or middle? Seems that several of them are like that. Example this fuel pressure and gas tank level also use the middle pin and the one on the left is blank.
Perhaps I should just run some of the connectors that came with the vintage gauge set directly to the engine?
