This thread is exactly what i need!!

what a genius James! I'm going to read this thread through properly to see if i can find the fault.

I retro fitted cruise to my 124 coupe, I know the actuator works, and the loom is brand new. The only possible things could be the stalk, the Amp, or speed sensor behind clock.

Nothing happens when i try to engage the stalk for cruise. The first day i tried it, the car accelerated when the stalk was lifted upwards, then tried to do it again and has been dead ever since -nothing.

tried replacing the black plug at the back of the amp as i have a brand new one, still aint nothing!
