Chevy installing a tachometer

Electrical problem
1999 Chevy S-10 6 cyl Two Wheel Drive Automatic 124,00 miles

My son has a 1999 Chevy S-10 4.3L V6 and wants to add a tachometer, I do not see a standard coil (round type) and was wondering where I hook up the wire for the tachometer to receive the RPM information.

I attached to the WHITE wire of the plug on the ignition model this plug has a 2 wires on it a white one and a pinkish one.
I do get signal but it seems low, curb ideal in park 5-600 RPM's Cold.
There is another plug on the igition module with 4 wires going to it and this also has a white wire.
Any assistance would be helpful.

Please see attached photo with the white arrow of where I attached the tachometer wire.

I have verified that the tachometer is set to 6 cycl.

Please give any advise on why I am reading low RPM's.
