Ok, I'm researching everything I need to put a pony package grille into my car (I'm either going to get a GT style, or trade a GT style for a pony package). Anyways, What I did learn is that they use different bulbs.... GT grilles and most aftermarket grilles use H10 bulbs, while the pony package grille uses H11 bulbs.
I was wondering how I would make a pony package grille work as I have the Raxiom foglight harness which has H10 plugs. Then I came across something. Factory pony package cars have "pigtails" to connect the foglights. I was wondering if a pony package owner could take a look at theirs and let me know if the factory just used one harness for both GT and V6 cars (with H10 sockets) and those "pigtails" are just adapters for the H11 bulbs. The part number on the pigtails is 5L5Z-15A211-AA.
