2001 OEM Toyota unit into 1993 Toyota ?

Hi all...I'm wanting to swap a 2001 Toyota Camry radio into my 1993 Toyota Landcruiser but I'm not sure how to match up the new style (2000+) head units molex plug (20 pin) to my old oem external amp (15pin) for "plug and play" simplicity. I understand Scosche and Metra make plug-in head unit and amp adapter harnesses for this, but I'm not exactly sure whats required (Scosche TA03, Metra 70-1761 ?)  Heres a link with pics for reference;

Old style "P500" 15-pin Molex: www.carstereohelp.net/wireharness_Toyota4.htm

New style "CN701" 20-pin Molex: www.carstereohelp.net/wireharness_Toyota5.htm

Additionally, can anyone confirm my suspicion that the secondary "CN702" 12-pin plug on the new unit is not used at all when an external amp is employed ?

Thanks very much...  

Did the camry have the 6 speaker system with the tweeters?  Or was it just a 4-speaker system?  And what kind of system was in the landcruiser?

I would think that actually that CN702 plug might possibly be used to send a signal to an LOC, rather than use high-level speaker outputs.  Still thinking about that part though...

I believe it had the 6 speaker option. The head unit is Toyota's optional am/fm/cass/6-CD indash 2DIN unit (made by JBL for Toyota) thats been available for the last couple years. They,ve been offering the same unit in the Camry, Tundra, 4-runner, Landcruiser etc, so I pretty sure its the same unit across the board...

...sorry, forgot the second part of the question. My 1993 LC had the oem am/fm/cass/CD with 9 speakers and 2 external amps (one behind glovebox for the drivers and one in rear for the sub). thx

TTT...

Anyone know if theres a better forum to answer this question (one with pro stereo installers or ?) - thx

First off, the connector labeled P750 on the 4th toyota page is basically the same as the connector labeled CN702 on the 5th toyota page.  I'm sure you probably already noticed that but just wanted to point that out.

Okay now for the landcruiser, you have just that one 15-pin plug coming out of the vehicle's wiring?  Or is there another plug as well?  If it's just one then the harness looks like the Best Kits BHA8110, right?

Another thing I should note:  USUALLY when you have those camry's with the tweeters, the wiring behind the radio is wierd.  For example, if you were trying to put an aftermarket deck in to the camry,  you'd begin by unpluggin the factory radio and removing that.  The two new plugs that were in the back of the factory radio are not the ones you use though.  You have to first unplug two connectors that are plugged in to the vehicle's wiring, just behind the radio.  Once you unplug these, the male connectors that remain stationary will just hook up to the standard toyota aftermarket harness (70-1761)and plug it in to the vehicle's wiring right where you had to unplug those connectors. 

Just FYI, if you tried to use a harness like the TA03 to hook up an aftermarket radio, rather than using the method described above, USUALLY you will end up getting a whole bunch of engine noise and weird sounds and stuff.  That TA03 harness with the RCA plugs is only for Avalons, not the camrys--at least as far as I know that's the case.

I have yet to see a reverse harness for these camry radios with the 6speaker system.  It'd be a female-ended plug that would match up to the CN701 connector on the 5th toyota page.  If you had access to the camry you could always clip the plugs off the factory wiring but most people don't like to do this as it kinda messes up the factory wiring.

Bottom Line:  Without a plug that can go into the back of your 01 camry's radio, there's no way to put the radio into a different vehicle.  Unless you solder a separate wire to each of the radio's pins, which I highly recommend against even attempting.

Guys..thanks for the info;

ES, yes I did notice the 15 pin plug is the same on old and new. I believe the 20 pin molex plug is the one I need since it appears to be the one that feeds the amp. Yup, looks like I need that new style $#@! 20pin molex plug.

Chris, unfortunately I never saw the donar Camry, just know thats the car the radio came from, but your right on that seperate amp harness.

I went to Toyota parts dept today and had them pull up schematics on the radio in question. Sho'nuf, theres a seperate modular amp harness with several plugs on it ($145), but theres also a  "Theft kit" ($40) thats comprised of just the 20-pin radio plug with 6" lead wires (yeah, I know...$40 fer just the plug "ohh how I love Toyota ! ). Apparently this is specifically made to replace radios that have been "cut" out. I'll just need to splice this into my existing amp harness.

Thanks all for the expert assistance !
