my friend , it has 3 kinds and 4 colors, please tell me which one do you want when you make the order, fit for motor, for 3   vat car, for 4 vat car,

AD-039-3 car / motorcycle / car digital display electronic tachometer. (also called idle, table) is shown the engine speed meter.Working voltage DC12V, display 0000-9999 turn.The engine sensor speed signal is processed by the filter and the single chip microcomputer is programmed to transmit the signal to the transistor and the digital tube is driven to work. It is characterized by wide operating voltage range, wide operating temperature range, high output load capacity, no need to debug.

AD-039-3A is suitable for frequency 16.66HZ/1000 of the turn of the four cylinder EFI car (two ignition) and two stroke, four stroke motorcycles.

AD-039-3B is suitable for the four cylinder car (with sub electric vehicle) with a frequency of 33.33HZ/1000.

AD-039-3C is suitable for the use of the three cylinder motor with frequency 25.00HZ/1000.

Be carefulPlease indicate the model or the model at the time of purchase. If you do not specify the default AD-039-A.

1: motorcycle wiring mode:

Red line connection power supply (+12V),

  black line; the cathode of a power supply (-12V, ground)

  green line signal line input. The signal line is connected with the ignition device to the high voltage pulse signal line (i.e., high pressure Bao Zhengji) or the output of the contact:

Note: signal lines do not pick in the high voltage output to spark plug the line, and all the high voltage line) or you will burn out the. Before then must understand before they can begin to. Proposed contact device or trigger coil.

2: electric vehicle wiring mode:

EFI car wiring:

Red line connection power +12V

The black line of the cathode of a power supply -12C (ground)

Input pin for the green line connecting the ignition coil

Digital tachometer test method: 12V battery, connect the positive and negative 0000, positive signal line touch will have digital changes, the normal form.
