so i have an 08 with projectors now and im thinking of buying some 05-07 heads...any wiring issues i will run into when trying to get em to work with my 08? thanks

 

Just for the low beams, if you have hid's...you can connect the 9006 bulb directly into the stock H11 harness. Its really simple and no pig tails were needed. The male connectors on the bulb just needs to be removed from the black plastic thats around it, which doesnt fit into the harness. You remove it by cutting it open and removing the connectors out of that black plastic. Then you can easily just directly plug it into the harness. Make sure to electrical tape it horizontally together and veritcally so it wouldnt get disconnected/water.

 

It's the same as if someone was swapping from 05-07 to 08. Low beams won't match, so either use HIDs or get conversion harnesses.
