Hello!

Trying to wrap up a coyote install. We're working on the speed dial box now.
We have a TKO 500 Tremek transmission. Pretty sure the speed sensor is on the passenger side toward the back.
The plug from the FFR rear harness that plugs into that has a green (speed sensor signal) wire and a grey (speed sensor return) wire.

Our confusion is, do we splice into the FFR harness green and grey wires with the green wire from the Ford speed dial box and the wire we added to the Ford Controls plug? So that the signal from the speed sensor runs both the speed dial box and the speedo??

I appreciate any advice.

Thanks,
Mike
