Speedometer? Cable driven or from Speed Sensor

My speedometer has "issues" when the car is cold - speedometer drops to zero then shoots up to actual speed a few times before settling down. How do I tell if it's electronic or cable driven? I've got a 1991 Convertible with cruise control.....I'm guessing electronic and it's time to pull the gauge cluster to clean the connections.....

p.s. even the Shop Manual ain't much help in this regard.....or the Haynes manual.....

I can't easily find where the speed sensor IS on my V6. Do I need to go from UNDER the car? If so, looks like ramps are in my future...LOL

So after drying out and cleaning the electrical connection at the speed sensor, all is right with Sunbird world. Now I will test the return policy at Rockauto!
