Yes, I am trading my JB4 Harness A for a DOWNGRADE to JB3. I bought it from my brother who used it for 3 months. Unfortuenetly i am unable to use the JB4 because on my car (F10) not having the right connections.
This doesnt mean you wouldnt have the right connections, it all depends on your car.
I am looking for a JB3 with USB & CAN tool For TRADE of my Jb4
