EX35 LED Turn Signal Conversion

[MizzouMaverick]

Let me start this out by saying I love my new EX35. This thing is amazing. I got it last month after totaling a Mustang Convertible. But anyways, here's my question.
I really don't like cars that have LED tail lights and then halogen turn signals or halogen high-mount brake lights. This car almost got it perfect, then they had to add those halogen turn signals at the bottom.
I would like to run a relay off of the rear turn signal wire, that would shut down any feed coming from the rear brake lights and flash between voltage and non, so that my turn signals would just make my LED brake lights flash.
Any ideas from master techs on how feasible this is, what parts I would need, and what wires I would want to tie into? If there was a nice replacement for that lower light, that was an LED block (not just a replacement bulb as those just aren't as nice as real LED replacements).

Thank you in advance,
Dave

I can't help you much, I have have limited experience when it comes to mods in general and virtually no knowledge on electrical mods.

As far as the wires you can tap into, I'd check the EXL file of the 2008 FSM for the electrical schematics and go from there: http://www.nicoclub.com/FSM/EX/2008/EXL.pdf

While I appreciate that and I have reviewed it previously, I don't think it will help much as this is more electrical questions. Allow me to elaborate.
I have a 12V flashing voltage for the flashers, and I need to apply that to the LEDs. Simple enough to move the wires, problem is, what if the brake lights are on. Now the brake lights are getting 12V from the brake signal, and a flashing 12V from the turn signal. I will need some type of relay that will bypass the 12V brake signal when the turn signal is issued, but the turn signal isn't a solid voltage to hold a relay (the relay would simply kick in and out with the turn signal). If I just used a relay on the brake signal powered by the turn signal, there would not be 12V to power the LEDs if the brake signal wasn't present.
Here are my thoughts. BS=Brake Signal, TS=Turn Signal
12V and BS into a double pull single throw relay, with a diode on the BS to not backfeed the 12V to the BS when the TS is active. The TS powers the relay, so that it will flash?
Not sure if I'm on the right track with this. I'm no electrical engineer. Maybe I should drop this project, lol.

Okay, so I haven't gotten much feedback so I've been doing a ton of thinking on this. I have attached a wiring schematic of what I think is my only option.
Here is my only issue with this idea. I don't know where to get a 12V signal that the L or R turn signal has been activated (a solid signal, as in before the flasher).
