Wait, what? The middle pin’s not the enable pin (eg, goes to the µC)?
Okay, whichever pin’s the enable, that’s the one you want to desolder’n’lift. 
Not ground, not the one that goes to the LED, the leftover one.
If you three don’t mind, could you draw into the below image of the driver I currently have
1. Where I would have to cut a trace to permanently disable the 3rd 7135
2. Or where I would have to wire in a switch to not permanently disable the 3rd 7135
3. And, most importantly, which “resistor divider” I could modify to disable the blinking low voltage warning
Thanks a lot in advance!
Otherwise, I could buy that bare-bones 7135*2 version from FastTech, but that’ll take three weeks : (
Your pic doesn’t work so I assume it looks like this.
If you want to have a switch for LVP too, remove the marked resistor , solder it in series with a switch and wire this to the pads where the resistor was. (Or, more simply, between the outer ring and pin 7 of the µC)
For permanently disabling LVP, just remove the resistor.
Perfect, thank you so much!
