Read the reviews! Several little details left out.

Need to trim a small bit of the plastic on the fuse panel in the footwell for the fuse to sit in far enough to make good connection. Als would have been nice to included a picture of the pin out on the ECM connector, but if you look at the backside you can see the row is marked #20 and you can over count from there... Just a bit nerve racking, and you do not have to remove the windshield wiper cowl. And also the ethanol content will not read out until the software is installed... So no way to assure its working until your load the new tune...

Overall was a pretty easy install.

Very good product overall. Instructions need work.

Need to give some consideration to RHD vehicles. Correct fuse box location is passenger side footwell, layout and routing of wiring is slightly different and a little tight. Turned into a 6 hour ordeal as things are slightly backwards.

As a reviewer above mentioned the ECU splice is slightly nerve wracking. My wires ended up being solid green and brown with green stripe. They were twisted together which made finding them okay....trying to see if they're pin 17 and 18 is nearly impossible.

Product seems to be working well so far.
