With a couple of different checks with a good digital meter you can probably get a good enough 'picture' of the signal to know if it will work with the cruise control.
Poolside; Please describe in layman's terms the tests you refure to here, I have the unit hooked up and passing the testing cycle but don't know how to check the pulse count. I am using the three prong plug under the beak on a 2009 GS as described in a nearlier post with a Rostra CC. I need the pulse count to set the dip switches to the proper range. The only reading I get with a digital meter set to VDC is 12V.
