Under the hood, near to the center of the vehicle, behind or just to the right of the air cleaner assembly there are three factory provided (for Where_do_you_connect_a_tach_on_a_1994_e350or optional upgrades) BLUNT ENDED wires. They usually have what appears to be about 1.5 inches of black heat-shrink on them.
One of them is white with a small pink stripe and is usually tagged as "CTO".
It is the Controlled Tachometer Output. A filtered circuit reducing interference from the other systems giving you a truer tachometer reading.
Most tachometer manufacturers use a Where_do_you_connect_a_tach_on_a_1994_e350wire for their TACH INPUT. Connect the green lead to the CTO wire.

i dont know whwere is the tachometer wire of 2001 ford windstar
The Tach sensor is connected to the positive terminal of the ignition coil at least that where my laser's factory tachometer is connected to. I believe Ghia and Sport models 1981 - 1984 have factory installed tachs
Instructions should come with the tach. Otherwise, contact the tach manufacturer.
