I want to buy it but...all his feedback are from buying things not selling. The CR2-12V is his first listing; price is good, but estimated shipping date says APRIL 11-20(2.5 MONTHS)?!?! Something may be wrong with my nose but I smell fish.
I think Ebay's refund policy expires before this date.

...All you need to do is purchase two small 5-pin 12V relays and connect the two as shown to represent the equivalence of the CR2-12V relay. I had to use a networking cable called CAT5E cable to extend the connection outside the switch, used a sealing tape to hold the relays . It might look rough but if you get the connection right, you stand not to loose the 60$. It is like thinking outside the box...

Any chance that you could please help us with a little circuit diagram for the "H Switch" wiring?
If it helps you help us, I've attached a jpg template you might use. You could open it in Paint and add your work.
If you need more reference, here's a couple links of PDFs from this thread that show the OEM CR2-12V diagram and workarounds:

ACTP vs CR
I combined the specs for the 8 pin ACTP and CR on the attached.
Top one is ACTP, bottom is CR. Pins are numbered for comparison.
As I read it:
Top one is ACTP, bottom is CR. Pins are numbered for comparison.
As I read it:
- The CR has 7 pins because the separate coils have pin 6 in common.
- The 8 terminal ACTP has an additional pin because the coils have no common pin. You can connect two of the coil pins as shown.

I ended up purchasing the relay off eBay for $60. It took about two weeks to arrive from China. I have to say it was well packed in a small plastic container with bubble wrap. I was able to desolder with some desolder wick bought from Amazon. I tried with a pump but the wick was more effective in removing all the solder. It took a little bit of time to get all the solder off to remove the old relay. Soldering the new relay was a breeze and after putting everything back together, the window worked perfectly. In addition, the indicator lights all lite up again. I may pick another one up later in case the passenger side fails. Thanks to all for the info and saving me hundreds of dollars! 😊

RX300 Window Problems Solved
I replaced the relays in both the driver side and passenger side of my Lexus RX300 with ACJ2112 relays after not being able to find a source for CR2-12V relays. I found the ACJ2112's on Ebay for $2 each. Thanks to everyone for previous posts on this thread. They were very helpful.

After trying unsuccessfully to find the CR2-12V, I ordered ACJ2112 relays from ebay for $2 each. 3 pins need to be linked together, and then the relay fits quite nicely upside down on the circuit board where the old relay was previously located, as long as you solder the wires in such a manner that they go downward from the relay to the board. I purchased a box of six differently colored solid-core 18 AWG wire and a new variable temp soldering iron on Ebay for this project, and it made it much easier. If you haven't already solved your problem, you may want to refer to my photos in my post at the end of this thread.

From the spec sheet it looks like ACJ replaces ACT. I can't keep up with Panasonic.
