i can buy a 05-09 sequential tail lights plug in for $50. will these fit on 99-04. If not could someone tell me why. Im assuming they have a different wiring harness, but could someone tell me why, looking to save money if possible lol thanks.

 

No they won't work, totally different setup
These will http://www.americanmuscle.com/sequen...lice-9604.html

 

Go with the plug in ones instead of the splice in from American Muscle.. Little more money but lots easier to install.

It looks like an easy mod to do yourself, but have patience. You pretty much have to remove all the trunk panels to get to the nuts holding the tail lights in.

Also, not on their description that they flash faster than the new model ones, but they sell a regulator separately if you want to change the speed.

 

thanks but i will get a plug in its easier

 

yea was never gonna go with a splice plug in is so easy. yea there faster and would def buy da flasher to slow it down
