edited april 30th for clarity.
First off, I'll attach all my lexus PDFs needed below and in the next two posts.
Starting with the easy stuff, the top computer screen, case, and connector.
computer 8326560220
case assembly 83240-60220
And whatever double din you need or want. It has come to my attention that the toyota OEM part is a way better part, if only in the fitment aspect of things. It's part number
#55412-60310 $58 partsouk, compared to the $30 ebay one. The same side adapters fit the stock part. So any adapters from ebay or amazon work with the stock piece.
All those above are the same for the landcruiser also.
The metal side brackets are the same as landcruiser 86208-60030 left hand, and 86207-60030 right hand. You can't reuse the old ones.
The lower section.
The panel that covers the whole thing and houses the small connectors for the cdl, hzrd an antenna +passenger side seatbelt/airbag light remains the same and covers up all the parts listed below.
The case holding the AC amp and the heater circuit board is listed as 55912-60140
That is one number off the totyota case.
The heater integration panel (circuit board) 84014-60210 (2003- jan 2006) This is the part listed on lexus sites. The late 2006-2007 part number is 84014-60340
I suspect maybe there is an addition to the later part number circuit wise, just like there is a break in production of the LC in Jan 2006 units. I have not found it in my LC books though.
EDIT april, 21, 2018.
It is a fact if your production date is after jan 2006 you must have 84014-60340 which is NLA, and I have not been able to find it anywhere here or international parts places.
There could be a fix by using the jan 2006 + production LC board. That would be a $600 bill to find out if it does or not. The circuitry is going to be in there for the additional passenger airbag on off indicator that is yellow.
First week of may I will have both the LC later board and the board/ assembly for a 2005 LX and I'll find out if you can put the landcruiser board into the plastic sub assembly and make it work with a different button arrangement.
Essentially re arranging the lower buttons to match up with the current LX arrangement. If you compare the LC and LX you'll see the lower buttons are in different spots on the lower panel. I'll know soon.
The AC amplifier has four different part numbers listed for UZJ100L-GNAGKA
88650-60820 , listed as 2003-2006 This one I don't know about and can't really find any info.
88650-60821 , listed as feb,2004-may2005 This one I can confirm that I've seen in an assembly listed for a 2005 landcruiser and is the correct configuration with the correct plugs that are in the LX and LC. And has been used in other conversions.
88650-60B80 , listed as may2005-2007 all.. this one I can confirm is correct and works in my LC. I would like someone to install this one in an LX 2003-4. I see no reason why it wouldn't work. But again, I have no proof. honestly, if someone put it the 88650-60821 and it turned out wrong or something didn't work right I could commit to swapping with you. I'm pretty confident that wither board will work fine, both were in non nav LC north america.
The MPH, distance, fuel econ, etc comes from the UART lines that go into the M12 connector. Also those lines dictate Fahrenheit in the upper right instead of C° (instrument panel dependent I think)
The lower front plastic panel.
Panel Sub Assembly- 55902-60130 this is lexus only of course. The knob kit for the lexus part is 55905-60760.
if you swapped to the toyota sub panel you'd have to switch side panel vents also, because then the lower cover wouldn't work, the one with the wood, or fake wood on it.
Connector info.
The AC connections in the lexus are A47, A48, and A49.
They are the same connectors as in the landcruiser, just numbered differently. Same part numbers though.
I have these and repair wires for the two needed.
The display connector M12 is the same as the LC and most of the wires needed for the new M12 connector come from the M5. I have these if you want them, either in a pluf an play along with the M5, or as a stand alone wire yourself configuration.
The m12 is a hard to find part I think. I only have one place where I ordered my lat set with a order minimum of $50, so I do in fact have a lot of these.
The combo meter, (instrument panel) connectors are the same as the LC, C14 is the leftmost connector, count over from there to C16 and were looking for pins 16 and 17.
THE 2003 LEXUS appears to have the combo meter pins moved up two positions to #14 and #15. These are the uart data lines. Do some reading, check TIS for 2003 specific, or check a 2003 FSM in the combo meter section for pin outs, the will for sure be listed in the FSM I just had some conflicting info about an Australian LXs pins being one off.
The C34 connector behind the display is the one that controls the antenna and hazrd, etc.
That's the one that gets cut and the some of the wires go into the A47 connector. (in the LC the same connector is labeled C28)
This is also where you would have a blue/white wire and a violet wire labeled as PAON and off (passenger air bag on, and off) those are also inserted in to the new A47 plug
I will never run out of A47 housings or the .64 III terminals for them.
