How to Modify Toyota 24 Cable into Toyota 27 Cable?

 Information on the new OBDSTAR CAN Direct kit Toyota immo system smart box data reading cables.

There are 2 different cables Toyota 24 and Toyota 27 cables. The Toyota 24 is for the Corolla 4A the 27 cable is for the 4A,8A-A9, 8A-AA Toyota vehicles.

The cables can be used with x300 dp plus/x300 pro4 to program Toyota 4A/8A proximity smart keys.

The ONLY difference between the two cables is that the corolla 4a has the red power wire in a different cavity them the Toyota 27 cable does.
You can take the Corolla 4a cable and add the red power wire to the connector and you will have converter the Corolla 4A cable to a Toyota 27 cable that works on all of them.
So if you bought one of those toyota bypass cables from other resources (ASK/UHS) it comes as a Corolla 4A cable, not the Toyota 27. So just add the red power wire and problem solved.

Here are some screen shots of step by step instructions to do the job.

smart ecu plug has change on the 2023. OBDSTAR added a post in the center by the release button. I’m going to snip that extra piece of plastic on a 2023 corolla cross. The CAN DIRECT cable and the online calculations are working spot on, no issue 2019 to 2022 on all (A9 A9 and AA AA) (BA BA is the newest no support).
On the plug itself only the power 12v changes.. terminal 3 is for Corolla only, and 4 is for RAV4, Avalon, 4runner, Highlander.
