For your truck, which has the TFI Ignition, I pulled this off of the AutoMeter Website.
Ford TFI (thick film integrated)
The green wire from the tach will connect to the green wire with a yellow stripe that is on the coil. This wire may also be either a solid green wire or a green wire with a white stripe.
I have a MSD 6AL on my truck, and it has the Tach Output. But the info above should help you.
