I just saw this thread last week... ordered the GM connector for my truck... it came with only a pigtail in it for the GND pin, with what seems like a diode in line under some tape. Am I safe if I just connect the rest of the connections direct and the GND have the diode? Also, I am having the darndest time locating the terminals to go in the connector. The GM Dealer wont sell them to me, claiming they are only for installer use, and online I see them with a minimum qty order of 3500?! Could use some help!! Thanks in advance... Truck is a 2007 (Newest Body Style) Silverado LT.
