The link to do this was posted above, ... rness-help You use a lexus integration harness. The stereo you are installing will need two sets of rca's to do it.

If you cant see the above link / arent a member of that site;

Metra 70-8112 is listed as TOYOTA AMPLIFIER INTEGRATION HARNESS 1992-UP. Compatible Vehicles: Lexus ES300 4DR Sedan 1992-1995. (But, it will work on the 1992-1993 Celica Sytem 10 and a few late manufactured 91's.


The same is true for BEST. Their part number is BHA-8112. Listed as 15 Pin Premium Sound w/RCA
1992-1999 Toyota.

I bought one off of ebay, although my car already has an aftermarket deck. I really hope the previous owner didnt butcher the wires to install it.
