This regards an 87 300D :

can someone advise me if the factory radio was removed and the little green speed wire is left disconnected, would this affect cruise ?

Ive got a green speed wire hanging behind cluster with a single female pin on it. I think at one time it went to radio but that radio is long gone.

Ive checked every pin on the cruise amp and manually jumped the actuator. It all seems normal, just no cruise. Is there a fuse somewhere? Although I get +12v at cruise amp pin so its gettin pwr. Just isnt doing anything...ofcourse the cruise amp was just replaced with a rebuilt unit. Still no luck.

I can take a pic of the wire if someone thinks they will know what it is.

This is an 87 300D turbo. Any help is greatly appreciated.
