Yes, the 2012 rav4 and 3rd gen sienna pinouts are compatible. But i thought you were targeting the '07 rav4 first?

If you're targeting the 2012 rav4 you probably want to sell it as the "3rd gen sienna" pinout. that's what everyone knows that pinout as for now. Otherwise you'll get people with earlier rav4 harnesses buying and complaining.
The design is already done and first prototypes for the 04-07 Rav adapter PCB are on their way to me. I was reviewing the pinouts for the later version "3rd gen Sienna" to begin the preliminary schematic design before laying out a PCB.

Thanks for that, I'll definitely be posting there once I have this tested out.

Gen3 Sienna/2012 Rav4 as well as 2nd revision of the 04-07 Rav4 version layouts are updated currently based on what I have learned so far, but will be waiting to get any boards made until I have fully tested the prototype unit I'm putting together.

I have a 2008 Rav4 and 2009 Rav4 . Eventually one of these is going to be a donor for my MR2. Will you have something compatible for one of these ECU's ?

According to this ecu diagram I found here: 06-12 Rav4 Wiring Diagram - the ecu pinout is the same on all of them from 06-2012 which matches up to what I have labelled as the the 0407 Rav4 version I have prototyped right now. According to the pinout I got off of Wilhelm the 2012 Rav4 is closer to what we are calling the G3 Sienna version. Regardless, it seems likely that one or the other should work for your needs.

I will say, if you are buying up ECUs to salvage connectors out of, do the rest of the community a favor and stick to the ECU's that aren't already hacked by Marc, just so as not to over tax the supply. The Rav4 ECUs are kinda hard to find as is. But if I remember right there are lots of Camry 2-plug ECUs that haven't been hacked yet and so nobody is looking for them to do swaps. Probably cheaper to buy for the connectors as well.
The Camry 4cyl and 6cyl ecu’s Are obviously super plentiful and also very cheap due to Immobilizers.
But that connector is used in all Toyota vehicles since 2007 ( a few before that) that use 2-plug ecu’s .

It seems 04-07 isn't a good year range for the first version adapter board. I will have to update that name to 06-12 possibly. Maybe just 06 Rav4 version. If others can post links to different year pinouts of interest (that they are swapping into their vehicles) in here that we can try to resolve the differences that would be great. I'm sure we can consolidate the information into a single spread sheet.

At least on the Rav4, 06-12 isn't going to work. I had to extensively repin my 2012 to match the 2007 pinout / ECU.

Do you have the part number of that 2012 ecu? Is it possible the engine/harness/ecu were made in 2012 as a 13 model year?
ECU is a 89661-0R280. It was advertised by the junk yard as a 2012 Rav4 that the motor came out of, so that's model year not necessarily manufacture year.

Toyo-diy searching for ECU part numbers year by year show various results with the 2012 coming up with 89661-0R280 for 12/2011-12/2012, while a reverse part number search shows 11/2008-12/2012. Ebay searches show 11-12 application. Definitely lots of conflicting information out there. No V6 rav4 after 2012 it looks like.

ToyoDIY is great, but the reverse part number search is a little confusing. For example, it will show 11/2008-12/2012 as the broad date range for that part number, but if you click on any one of those it will take you to the diagram / parts list for a 2008 and it will show a different part number.

I think the reverse search will basically give you the date range for the generation / sub generation (face lift versions, which '08 was) to which the part is applicable, but if there is a change within a generation it won't break it down to that level of detail.
