    Aftermarket tach power?
    « on: September 29, 2013 - 04:01:25 PM »
    Trying to install an aftermarket tach and need to find power only when car is running.
    I would like to tie it to the fuse block. There are 2 open slots, one marked acc and one marked batt.
    Do one of these only power up when car is running?
    There at the bottom of pic.

    The ACC has power when the key is on. It would be a good place for tach power
