Wiring diagram for just power window switch??
 

There are 5 wires to each passenger side power window switch. Does anyone know which colors are power & ground off-hand?

EDIT: I updated the wires with their known position in the harness/connector

We have:
- grey - 2 UNKNOWN (illumination?)
- lavender with red stripe - 4 DOWN
- lavender with white stripe - 5 UP
- white with black stripe - 7 GROUND
- lavender with green stripe - 8 AUTO

for RF switch. I'm going to *guess* that the red stripe is power and black stripe is ground. Can do testing myself of course but wondering if anyone knows for sure.

RR door has:
- green wire - 2 UNKNOWN (illumination?)
- lavender with red stripe - 4 DOWN
- lavender with black stripe - 5 UP
- white with black stripe - 7 GROUND
- lavender wire - 8 AUTO

My plan is to use that power to power my ambient lights in place of using the stock ambient wire power.

Wiring diagrams from the Lexus ES (XZ10) Service Manual for the Front Passenger Side Power Window, Rear Power Window RH, Rear Power Window LH, and an overall Power Window system wiring diagram (scroll down the page some for the wring diagram). The TERMINALS OF ECU page (scroll down to see J5, L4, and L10 connectors) has some wiring color info for the auxiliary battery power supply, Ground, and LIN communication line wire colors.

Thanks for the links. From my reading it appears the white with black stripes are indeed ground wires but I'm not sure there is a 12V ignition wire. There is one wire on each connection that is not accounted for (pin 2 green on RR and pin 2 grey on RF). The diagram that shows the LIN communication line doesn't specify which wire it is on the switches, just the regulators. Hmm....

EDIT: I just realized that unknown wire must be for illumination!

I should bookmark that link.

It looks like I might need to find a different wire in the door that provides 12V accessory power...

How much power/amperage is your ambient lighting going to draw for each door?

If there's enough ampere margin in the fuse for the power window circuit then you might be able to to tap into each power window circuit's auxiliary battery power line and use a voltage controlled switch to control suppling power to your custom ambient lighting. Tap into the OEM ambient lighting circuit on each door for the voltage that will turn the switch on or off. (There's various types of voltage controlled switches. The type I think you need is one that is a binary full on or full off type that switches at a predetermined threshold voltage. With something like that, your custom ambient lighting will have an unrestricted power supply when the dash illumination and OEM ambient lighting has been turned on/up to a sufficient level to trigger the voltage controlled switches.)

Found an additional Lexus ES (XZ10) Service Manual TERMINALS OF ECU with additional wiring colors. Except for pin 8 AUTO your wire colors match up with the service manual's. The exceptions: J3 connector (front passenger door) pin 8 AUTO wire color is listed as "LA-G" wire color and both L1 connector (right rear door) and L7 connector (left rear door) pin 8 AUTOs are listed as "LA-GR" wire color.

In looking again, I think pin 8 on RF it may be lavender with a green stripe. I am a touch colorblind moreso with brown-beige type colors.

hello, do you know which wire provide 12v for ambient light?

im also doing ambient lighting bro please tell me if you found a solution to
 

im also doing ambient lighting bro please tell me if you found a solution to the 12v problem. I could only find 5 volts max unfortunately
