It looks like the original 14615 transmission was replaced with a 12609B sometime after 1991. The speedometer cable, is not hooked up. Assuming the cable is unbroken inside the casing, can I just hook it up to make it work again? And the odometer as well?

I quess that you have the drive gear and worn gear in the trans and not set up for a sensor.If so then you can conect to speed o head and then you will have to have a adapter gear box on the trans so you can connect the cable to it. The speed adapter is what calibrates the speed o meter to the ratio rear ends you have.

In other words, I can't just hook it up. The cable is there, dangling, and looks like it fits into the receptacle on the top of the transmission. But I need to get some kind of adapter?

You do need a adapter to use but i dont know if you have one on it or not and if you dont know what one looks like post a photo of the rear of the trans where you think the cable should hook and we can tell you if you have a adapter gear box or not. glenn
