speedometer cable routing

[BFR]

how is the speedo cable routed up the firewall? Is it between the legs of the heater ducting box mounted to the firewall?

The speedo cable comes through the floor behind the fuel pedal at the firewall,where the trans cover is bolted to the floor,then runs up the firewall behind the heater ducting

thanks, it turns out the the forward part of my tranny cover is from a 5ton & made it look like it should have been on the passenger side.
