I have 2 different electronic flashers. Nothing special for either. One came from ebay and just plugged in; the other from BTR, and had a ground wire with a slot for a screw. I used an existing nearby screw on the steering column.
I do notice that at least my indicators blink once or twice after I cancel the blinker, otherwise all good.
