I got one of the cheapy ones from Amazon. I have limited expectations for longevity, so we'll see.
Mounted the relay box on the firewall between the Heater controls and the wipe motor. I had taken out the piping to the rear heater so had a little more room there. Then extended the relay out puts to a terminal block I mounted to the support bracket from the cruise control.
The buttons I mounted on the overhead console that I changed out from the original '96 style.
Where did you relocate the cruise control module to?
