3-door smart key feature on v ( lowercase v) five retrofit for v three?

I asked this in the electronics, but little or no response, I have searched, but have found nothing. The v (lowercase v) three comes with the 1-door smart key feature, and I was wondering if an upgrade to the 3-door feature that the v five comes with is even possible? I would imagine that the module is the same, just need the sensors on the passenger door and hatch? has anyone done this?

 

Thank you!

 

Update: I have ordered all of the parts, and have confirmed that there is no wiring harness on the Prius v ( lowercase v ), so hopefully the connection for the passenger side door handle is wireless, we will see once I get the parts in and start taking the car apart!

 

Update: I opened up the passenger door panel and took a look inside. The v needs a wiring harness for the passenger side door. However, it is not sold separately for the v for some strange reason. It is sold as part of the entire wiring kit for the door. Since that kit costs about $250, I decided to order the wiring harness for the regular Prius in hopes that it works since its only $40. The reality is that it looks like its only one wire that needs to be connected, so if the harness doesnt work, I will probably just figure out a way to connect the door handle to the connector that is in the door. I will keep everyone updated.

 

Update: The regular Prius wire harness works, both connectors fit, now its just a matter of wiring it up, the car is in the body shop getting some work done, so it might be a few weeks before the install is complete. I will keep everyone posted.

 

Ok, got my car back, I will try and finish this up on Sunday, all wires are ran, now its just a matter of connecting everything and testing

 

Update: The wires on the Gen III Prius and the Prius v do not correspond, there is only one wire coming out of the passenger side door on the v, where there is 6 on the Gen III. Also, the ECU connector wires do not match up, so I am stuck at this point unless someone else knows, or has done this to a v. I will continue to investigate this, and have sent a message to the person who figured this out for the Gen III. It seems like I might be able to wire the rear hatch, so I will give that a try. What would be extremely helpful is if someone has a v 5 that would be willing to take apart their passenger side door panel, to see how it is wired. I will not quit until this is done and works!!!

 

Update: I went to techinfo.toyota.com and bought a 2 day subscription, downloaded the wiring diagrams for the v (lowercase v) and the Gen III, and noticed a few small differences on wire colors and pin placements. The main difference is that all of the wires from the wire harness on the passenger side door must be ran through the door into the footwell of the passenger side and then connected to the Certification ECU connector. If anyone does this, just make sure you document which wire is which before you put the door panel back on. I connected everything according to BrettS excellent instructions, and everything works except for the opening of the rear hatch when the car is locked. I can lock all doors from the small button on the rear hatch, but it wont open when the car is locked. The passenger door opens and locks when your hand is present on the sensor on the door handle just like the driver side. I will continue to troubleshoot this issue, and hopefully get it resolved soon.

Ok, I figured it out! It now works perfectly! If anyone wants to try this on a v, I will post the different wire color connections, and different steps that need to be taken as compared to BrettS's excellent write up for the Gen III Prius
