It is all plug and play, no splicing of wires. The most difficult part are removing the panels and being careful not to break anything. It took me like 3-4 hours. It was my first time dismantling the dash.
After everything is installed you need to program the ecu. You can go to the dealership to have this done or you can do it on your own.
I bought a "VXDIAG VCX Nano Toyota and Lexus Diagnose and Programming Tool Compatible with J2534" ($80 from amazon) it comes with Techstream software from toyota. Installed it on an old laptop running windows xp and programming done in 5mins.
Thanks for the info, I've been looking at the OEM one for a while and debating if I wanted to rip everything apart, was hoping it was plug and play
