Tachometer wire

I am looking for the wire that connect to the coil for the tack on the fire wall,
The car now has a HEI system with a tach conection.
What color wire should I be looking for. how can I test the wires to make sure I find the right one.
The car is a 65 GTO with Auto trans.
thanks

Stock tach or aftermarket. Stock tach won't read correct with HEI. I have and MSD system and had to buy a tach adapter to make it work right.
