Depending on your point of view, we can either thank or blame Thunderbird designers for starting this whole sequential taillight thing, where each side's innermost bulb lights first, followed in rapid succession by the middle and outer elements. Before long, the Shelby organization borrowed the idea--and some '65 T-bird taillight assemblies--for the '68 GT350 and GT500. But it was Classic Design Concepts that brought the, uh, design concept to the mainstream, making sequential adapter kits for every Mustang variation since 1994. We kinda figured it wouldn't take CDC long to whip up a version for the new Mustang, and for once we weren't wrong.

CDC's 2005 Dynamite Stick Sequentials kit consists of two near plug-and-play harnesses, one each for the left and right taillight assemblies. They're not entirely "plug and play" simply because one additional wire must be run to the innermost bulb on each assembly. Even so, installation is a breeze.

Coming up with the 2005 "Dynamite Stick" sequentials was more of a challenge than you might think, however, since the S197's method of signal/flasher control is a radical departure from past practice. Whereas every previous Mustang used some form of flasher module to oversee turn-signal function, on the '05 this is just one more duty of the all-knowing, all-seeing Spanish Oak processor, requiring a whole new electrical approach to making the sequentials work. The good news is, we don't have to care about the hurdles CDC had to clear to make these things work; we just have to enjoy two particular benefits. First, the purchase process no longer requires shipping your old taillights to CDC as cores, and second, turn-signal interval is no longer slowed by the sequential operation. There is no bad news.

CDC's Dynamite Stick sequential kit is not much more complicated than a pair of electronic-module-equipped harnesses to be plugged inline between each taillight assembly and its chassis wiring harness. We say "not much more complicated" because there is a single lead to be run to the innermost bulb on each side's lamp assembly. This step is necessary, as this inner bulb is not used for brake or turn-signal function in the factory scheme of things. But don't sweat it; explaining this procedure probably takes longer than performing it, so let's get on with a look at the kit and its installation.
