ULF-44 Wiring Question

I'm currently running ULF-44's because of the dual pattern feature.  What I really want is the ability to steady burn while keeping the two pattern option.  It occurred to me that I could simply add a wire for (+)to the point where the LEDs connect to the ULF.  If I didn't apply (+) I could get the normal patterns but I could steady burn the lights if I wanted to.

My question is if there are any issues with possibly backfeeding electricity into the flasher?  Do I need to add diodes to prevent backfeeding?  Has anyone tried to do this?

I've done the same thing on a few installs not sure if feedback is an issue as I've always put a diode in to prevent any feedback. Always better safe than sorry.
