It is normal for a Wiggy to trip a GFI when connected to the hot and ground but not neutral and ground. Is the GFI protection a receptacle or blank face type? Have your checked for voltage between ground and neutral on both the line and load side of the GFI? Could the line or load be connected in reverse polarity on the GFI? On most GFI receptacles the both hots connect on one side and both neutrals connect on the other but I know there is at lease one manufacture the has the terminals criss-crossed. I have seen these wired in reverse many times and think it was a very poor design choice for the manufacture. Anyway this was just a thought. Good luck!
