Good quality connectors
Used to add a OBD2 scanner where the OBD2 socket was already occupied by a feed to the alarm system. Works perfectly but don't forget to tell your alarm company if the vehicle is monitored as the alarm will go off as soon as the plug is pulled! Nice low profile plugs and sockets. A lot of cable to fit in but some people will need this.

My expensive OBD diagnostic scanner didn't work but a cheap basic with limited functions did.
I don't think all the pins are wired to the obd connector on cars.

bbfly-B4 OBD II OBD2 16 Pin Splitter Extension
I used the spliter on my Range Rover as I need to keep an Nitro OBD11 adapter permantently plugged in and I need to use the data socket when needed. So this was the outcome, works fine too. Thanks

Perfecto...
Works well and no issue. I have connected race chip and display screen and they both work smoothly with this cable. Quality is good and strong cables.

Does exactly what it says on the tin
Bought this to be able to connect multiple devices into the OBD port on my car at the same time, works fine, no problems at all. Just what i was looking for.

Ok, but tempramental
OK length, flat cable and low plug profile. Unfortunately, not the best fit on my car's OBD2 port - if I push it fully on to the port in the car, it doesn't work at all, but if I ease it back out a little, it does work, so perhaps I have a faulty pin or two, but due to work commitments I haven't had chance to investigate yet. None of my other OBD cables behave in this way, so the issue has to be on the cable.

La verdad, por el precio, muy buen cable. Lo tengo puesto en un Seat León modelo de 2017 para conectar un aparato que a parte de controlar varios parámetros hace también de dashcam y además tengo puesto un emisor bluetooth para conectar con una app de mi teléfono. Y funciona a la perfección. SalU2!
