on a memory tach do you run the red power wire to a hot wire or off the switch are you suposed to read the max while the car is still running or does it store it thru a constant hot wire that saves it and reads while the motor is shut down?

One wire to the switch one ground wire the other goes to your distributor. The memory will be recalled with the motor off if you turn your switch on.

If it is an Autometer tach then their website has wiring diagrams for just about everything they've ever made.

I have a separate "gauge switch"I hooked the light and the red wire to that switch so I could turn it on and off.Hope this helps.
