Ford's G.E.M. May Drop A Low Signal Across The Dome Light And In Most Cases Cause A False Trigger.
To Eliminate This Cut the Door Pin Trigger Wires At The G.E.M. And Insert A One-Amp Diode With Band Side Faceing Doors.
Make Your Isolated Connection On The Door Pin Side.
The GEM (Generic Electronic Module) Is To The Left Of The Radio.Door Pin Wires:YELLOW/BLACK (DR), GRAY/RED (PS)

Also, Be sure you are Waking the G.E.M. everytime......( Bad Connection ??)

.To Wake Up The G.E.M Send A Negative Pulse To The YELLOW/BLACK Driver Door Pin Wire With The Unlock Pulse. Diode Isolate Cathode Band Side Of Diode Faces Away From Vehicle Wires. YELLOW/BLACK Found At The Central Security Module Behind Dash Panel, RH Side.
