Lexus GS 450h Sport Radar Cruise Control Retrofit

I'd assume that US has more GS350 models than Europe... quickly searched the eBay with part number 8824030420 and there was few used modules available...

I have an update.  I ended up buying the distance control ECU (88240-30410) from a Lithuanian breaker on eBay.  I did try to reach out to a couple sellers on Ovoko.  They did say that they can ship to the US.  But I didn’t hear anything more when I asked them to send me an invoice.

 

Anyway, I received the part earlier this week and everything works now!  I did buy the part for a RHD model, but I already had the ECU from a LHD 450h, so I just switched the housing over.  I do have an IS steering wheel installed, so I’m using the sport button to change the following distance.  Thanks everyone (especially Sami) for the help!  For anyone wanting to do this mod with a RHD 450h, I do have a distance control ECU for cheap.

Unfortunately, I didn’t see any when I was searching.  A lot of the listings mislabeled the normal cruise control module as the distance control ECU.  The US probably got more of the 350, but the PCS option was almost always only found on the 450h since it was the most expensive GS at the time.
