Tach signal for boost-it box

[champyfz450]

Hey guys I'm hopin someone might be able to tell me where I can get the tach signal from on the older cfi4 motor so I can finish the install. It is different than the pro wiring in the instructions. Thanks

There is a solid white wire in a four pin plug coming from the magneto. It's a different plug than the cfi2 motor but the white wire is there.
