left4deadkillez Posted September 26, 2017 Report Share Posted September 26, 2017 Working on installing a new tach and harness and came across a speed amp. Any Ideas? Quote Link to comment

wayno Posted September 26, 2017 Report Share Posted September 26, 2017 Maybe it has something to do with "speed amplitude". Quote Link to comment
datsunaholic Posted September 26, 2017 Report Share Posted September 26, 2017 Well, in a Diamante it was the device that turned the radio volume up when you went over 15mph. On a Datsun, it's a system including a switch in the speedometer that allows the carb to drop to idle. On a 210 it's a 40mph switch along with the throttle opener solenoid. Quote Link to comment
