I imagine this question have been answered a dozen times so my apologies.... I just can't seem to find the answers.

I'd like to install a cruise control and have contacted thecruisecontrolstore.com for guidance. Their question is: "Do you know if it (speedometer) has a buffered speed signal output? The electronic throttle cruise kits are software based. We only have a handful of softwares built around a few different speed signals. We have to know the speed signal or we will have to glue magnets on a drive shaft."

I have a Mk3.1 with a 302, factory/Ford EFI, and a Speedhut speedometer (not GPS). I suspect I need to take the magnet on drive shaft approach given the comments I've found here but just want to be sure (and not create extra work for myself).

Thanks in advance and Merry Christmas!!
