We run a wireless Flightdeck upfront, and a wired Cateye in rear. Cable run is fairly simply with a little matching electrical tape. I also use my Garmin on occasion. The speed/cadence sensor fits, but magnet placement on the stoker crank is difficult. I used a super magnet from RS attached with silicon, it lasted a couple months. Transmission was strong enough for front or rear mount of the receiver.
