I've been wanting to put a counter on my LnL, did a little googling and found a couple video's using a cheap punch counter. https://www.amazon.com/gp/product/B01875612U/ref=ppx_yo_dt_b_asin_title_o00__o00_s00?ie=UTF8&psc=1 It's a pretty cool little deal. Mount the sensor, stick the magnet to something and attach the wires to the LCD display. I already had a hole in my bench so that's where I mounted the sensor which is a good spot since right behind the press handle is kind of dead space already. I just stuck the magnet to the side of the primer slide piece. This is how I wired it up and it seems to work. The counter came with no instructions and most of the writing on the LCD display is Chinese. There's a metal bracket on the back of the display for mounting, battery compartment is under this plate. I used the plate to hold the wires and take any stress off the wire connections since I'm just setting the display on my bench. Most of the videos I watched on this counter mentioned that there's no off switch and the display is always on. I found that if you press the pause button and wait 30 seconds ish the display turns off, once the pause button is pressed again the display comes on displaying the number it was pause at ready to start counting again.
