Ok i just recived my PIAA H1and im trying to install them in my 06 6mt sedan Ive gotten the inner fender out and gotten to the bulbs buti think I bought the wrong bulb or something because the one thats in there now has 3 prongs on it and the new ones only have one and there alot smaller to? Can anyone give me some insight into what imdoing wrong i can post pics if need be.

 

The bulb you need is the H4 the 06 coupe uses H1. Hopefully you can take them back to exchange them. Check out codeflux's post on his H4 install.
