Hello,
I recently picked up a set of 2011 ISF interior trim for my 2007 IS350. I knew buying them that the window switches would not be plug-and-play because in 2009 they changed the connectors. I was hoping someone could post pictures of the pinouts for the window switch connectors for a 2007 and a 2010 250/350 so I can figure out how to rewire my car for these switches. Or if anyone has done this window switch conversion, feel free to chime in. Thanks in advance.

 

I’m also going to try fitting 09+ switches to my 06, but it’s not going to be easy. From what I’ve gathered from the wiring diagrams, I think you’re also going to need the 09+ window motors at a minimum, and probably the door wiring as well.

 

Please help these guys out with this cause I would love to do the retrofit too

 

I can pull up diagrams for 2013 as I have a subscription at www.alldatdiy.com but someone needs to do the same on TIS. I think its $25 for 2 days of access. Im not certain they have a restriction like my site and any vehicles can be entered. https://techinfo.toyota.com

 

I did some more investigating using the wiring diagrams and put together an Excel file with the pinouts for all the relevant components.

It seems that for 2009+ they moved the logic for the AUTO function from the window switch to the window motor. The switch now only uses the UP/DOWN/AUTO signals to communicate with the motor (2006 used 3 additional pins, PLS1, PLS2 and SSRB for sensing the limit positions). Another major difference is that the 2009+ power window master switch now communicates directly to the window motors via the LIN bus, completely bypassing the other switches. For 2006 cars, the master switch communicated to the other switches using the BEAN bus.
However, on 2006's there's also the PWS pin on the master switch that seems to be connected in the same way to the slave switches as the LIN pin on the 2009 version. I'm not sure what signal gets sent on this pin, maybe someone can probe it and find out.
On the 2006, the LIN equivalent pins on the slave switches seem to be PCT and PCTI, as they're connected the same way to the L/H and R/H junction boxes. In theory, one might be able to replace the window switches and the window motors and reroute the wires previously used by the PCT/PCTI pins to the LIN pins. An additional wire would also be needed from the master switch to the LH window motor for the LIN bus.

By the way, here are some interesting facts about this change:

 

For a second post, that's impressive. Is the new car spec sheet from TIS? I'd like to find this about the A760E transmission. The white paper if you will.

Thanks

 

Yes, it's from TIS. A while ago I paid for 1hr of access on lexus-tech.eu and took as many screenshots as I could, for future reference.
I also have an older IS250 manual saved for offline use, but I couldn't find anything regarding the A760E. However, I did find some info in the GS300/GS430 manual. I can PM you the files if you want.

 

Okay, knowing the source is the key ingredient I'll pay and dig into it on some rainy night. Thanks much...
