Joying head unit (non-nav) (1 Viewer)

[gx470weekender]

Alright- bought a Joying head unit for my 2003 GX470. I know their site says 2004 and up, but I know some 2003 owners have had success. Tried installing tonight with no luck due to mismatched wiring harness connectors. I’m curious if they sent the wrong harness, or if I’m just going to have to retrofit the wiring myself.
Here is the back of my stock Lexus/Pioneer radio/CD/tape head unit - is it the same as 2004+?

Here are my stock three connectors (the left one does connect to the Joying harness - it plugs into the center spot in the stock unit above):

Does this match anyone’s 2004+?

Here are the Joying connectors (again the left one is the only one which matches the left one above):

If I’m out of luck, does anyone have a stock wiring diagram for an early GX? It seems the diagrams I’m finding online are 2004 or 2006 and newer.

Thanks in advance!

There were like 3 options from Joying for the correct adapter. IIRC we had to find the amp under the drivers seat to make sure we were ordering the right one.

Here is the back of my 05 factory head unit with Pioneer amp. I have an older MicroNavi unit.

Only 2 of the 3 are reused. You do need the CAN BUS version to connect to factory Pioneer or Mark Levinson.
