Sequential Tails

Late to this discussion.
Whether to plug in an adapter or run a wire to connect the lights to J393 is really a personal choice. Each has its good and not-so-good sides.
Plugging in an adapter is the easiest and fastest way to do it. All you need is to pull out the panel that's covering the rear gate, replace the lights and plug in the modules.
For people (like me) that wants to let the car itself to control the sequential signal (as oppose to plug in a 3rd party module), running a line is the way to go. But it involves more intensive work and would need about 3-4 hours to finish.
Both ways, according to my tests, if the module fails, the turn signals will lose the sequential effect. If the wire fails (or broken for whatever reason), the turn signals will lose the sequential effect. So I would say both solutions can achieve the same result, it's just up to your personal choice. BUT, think it this way. What's the chance of something goes wrong? A fixed cable or a 3rd party module? Yes, it would take more time to run the wire, but it's almost guaranteed this would be a one time thing. On the other hand, you saved some time and effort by going the 3rd party module option at the beginning, but if it goes wrong, you'll have to open up the back cover and do it again. And what if only one of the modules goes wrong, you will have one side shows sequential signal while the other side doesn't.
And yes, with either solution, you'll need the coding to separate the brake lights and turn signals. That's the very first step you need to achieve.

I actually like the method Steven has as well. Either way as long as no wires are cut and it can be reverted back to factory, I like it. I never minded gutting a vehicle to run factory wiring to various components....

Several shops in North America have recently purchased VCP (Vag Can Pro) which should make these conversions a little easier/less costly. Also a fair number of VCP interfaces have been purchased so enthusiasts who are willing to share can also assist customers who do not want the added cost of purchasing the interface.
