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.

The white wire at the coil is the right one. Make sure the setting on the tach is set correctly.

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.
