wierd tach signal hookup

I am trying to install a remote starter into a 1998 Mercury Villager. The manual says to wrap the tach signal input wire around the high ignition coil wire 5-7 times. I have installed remote starters in my other cars before, and the tach signal wire was always soldered directly to a bare wire in the ECU or tachometer, not just wrapped around the ignition coil wire. Has anyone installed a remote start with this kind of tach signal input before? The manual sucks, it is basically just a 1 page diagram. All I see is a picture of this wire being coiled around the "high coil" and the words "loop 5-7 times". Everything else is wired already and working, except for this wire. Do I just wrap it around the wire coming from the ignition coil to the distributor? What other wire could I use to coil this input wire around? I'm pretty sure its not meant to tap directly to the wire, but rather pickup signal through the insulation like how the clip on timing guns do. It is a solid copper wire and not stranded like the rest of the wiring. Thanks for any input.

Always check info with a digital multimeter.

I promise to be good.
