viper 5901 flash turn signals

*EDIT*: Just realized that if I wired 12v to the RED / BLU and BRN wires at the LED mirror turn signals, the rest of the turn signals will probably go on as well. How would I prevent this from happening and only have the LED mirror signals flash?

That could all work. Just disconnect from the hazard wire and use that to control the 2 mirror lights. You just need to add 4 more diodes so you keep the turn signals seperated. (diodes are fun...right?) See my wiring diagram below. Note, you will actually have to cut the RED / BLU and BRN wires and put a diode in between the two ends to pull this off.   Let me know if you have any questions.

Thanks for the diagram sparkyssb, I will give it a try
