				Convertible top speed sensor
			 
 
			I have a 2004 Boxster S and recently splurged for a SmartTop relay. While playing around with it, I've discovered that with the SmartTop, I am able to raise or lower the top while moving at any speed (0-60+). 
 When I go back to the stock relay, I can pull the e-brake up a couple of clicks until the light comes on and then I can raise/lower the top no matter the speed.
 
 How can I troubleshoot the speed sensor?
