This is where the speedometer sensor goes into the tranny. If you get larger tires or differnet gearing, you just need to swap out the gear that's attached to this cable. Removing this cable from the tranny is as simple as unbolting one bolt. Pretty easy.

Underbody view of the trans and one of the header collectors.

Cruise-o-matic cross member.

Shift linkage still needing to be attached (this will get done after the headers get installed).

Finishing up the install at night.
