530T Auto Vent Problem Cured - Tip

Today I was installing a 500ESP with a 530T on my 2001 F-150 and almost every time I armed the system the windows rolled up then vented. Well that ok if it was when the temperature is hot but this does it on its own so I checked the connections,changed the dipswitch settings and even the module &it still did it .Well for the hell of it I cut the aux wire (RED / white) and the problem STOPPED I checked the wire off the 500 and sure enough when arming there is a small pulse almost barely noticable but enough to trip the 530T to vent so I used a relay and it stopeed auto ventin and everything worked the way it was supposed to.
