I have a set of the DP Mirrors with integrated blinkers, so I'll have a look at it soon.
Do you know what wattage each bulb is?
I assume the the LEDs in the DP mirrors is the same as in the LEDs in the handguards which would be 3.11 W...?
If so, connecting both would draw 6.22 W front the front indicators and 10 W from the rear, which would be too much.
Reading through the other posts it seems that if the indicators draw more current then the standard setup, then they will not work...
have a look at wiring diagrams..
