By "Vans strobe", to you mean the AeroLED Nav/Strobe SunTail? If so, you'll just power it directly from the individual nav and strobe switches. The wingtip FlyLED nav lights can also be powered directly from the nav switch but the strobes, landing and taxi lights need to go through the control board. If you want the option to power the wing nav lights for extra taxi lighting, they will need to go through the control board.
Feel free to PM if you have any questions.
