Hi friends
Finally I successfully fit digital seven segment Tacho on my Alto.

I got this from ebay. Check it

1) locate the tacho signal Brown color wire.
2) Place SSD counter counter in dash
3) wire them together.

there are two settings for divider value and rotation / frequency selection must be done with switches on tacho. It is explained in the ebay item description.

4) Also I checked with bluetooth OBD connector and Torque android program on my phone.
it gives correct RPM.

Wow !! So which OBD are you using ? Can you please check in any 800 and let me know if it works.

Can we connect this RPM gauge to ignition coil as my car doesn't have any wire / signal from ECU for RPM.

according to description in ebay it can read pulses (even high voltage) but i did not receive any manual or document when i purchase it. but if we can input any pulse, I think it can count it...... but there is meters directly read data from ignition coil check this

Also please check if the obd works with 800.
