To install, you need to remove a lot of screws to loosen the wiring harness. A hook driver like the one below makes life a lot easier when disconnecting the plugs (pull back the grey tab, hold it down and slide out the connection). Unless you're mechanically inclined and patient, I'd suggest having someone else/paying to get it done.

I can attest that the JB4 is just as fast, in some cases faster, than a full flash+CPC+TCU at a fraction of the cost. It is tough to install but can be done with great patience.
