Bro yung sa website ok yung project na yun if you can get the parts and masipag ka to install it. I do this for industrial machines. As you can see sa site nasa injector yung install nung sensor. You are are basically getting the rev/min of a shaft using a reflective material and a photosensor. Dun sa sensor you have 2 wires for supply and a single wire for output na naka kabit sa analog tachometer. yung alternator mo may W na wire? you can place a voltmeter measured against ground to see ano yung output dun. try revving the engine and see the output. kung wala or erratic then most prob its a frequency output (pulses) or digital output(on/off). Post the connection nung tach mo and the alternator and lets see how we can do it.

para sa mga gsto mo maglagay ng tach sa 4d56 , eto po ung gagawin
1. buy a diesel tachometer (auto gauge na brand sa concorde avail.)
2. check kung may W terminal ung alternator pag wala ask an automotive electrician to make one for you basically you just tap wires on the diodes.(wizzard does this *800php kasama baba ng alternator)
3. tapos connect the wires na follow the manual of the tach adding a fuse to the positive terminal of the tach would really be benificial.

just an update on the installation , ung wires sa gilid ng injector pump can be used as source ng rpm , i have just tested it a while ago , it works better and more accurate than the ones in the alternator, all u have to do is tap ur tach on the white wire on the side of the injection pump.
the other connection was made sa alternator ko , they made me a W terminal , most auto electrical shops could do it

2 wires coming from the injection pump? wheres the connection of the other one?
