2003 Tundra SR5 Stereo Amp question (Long)

My son had an aftermarket DVD/Stereo player installed by a local audio
system installer. He decided to reinstall the original factory unit
(according to the VIN #, Deluxe AM/FM CD player ). He is the original
owner, since it was new off the lot. The stereo/ventilation controls were
easy to remove, however the the connectors on the main wiring harness did
not match the connectors on the original stereo. I took some detailed
pictures of all harness connectors and stereo connectors and went to my
local Toyota dealer parts dept and inquired about the problem. I guessed
that there may be an intermediate cable between the main harness and the
stereo. One of the employees knowlegable about stereo installation in
Toyotas, said there was no such cabling and should be an amplifier the main
harness connects TO and the connectors FROM the amplifier connect to the
stereo. The amp is supposed to be located below the stereo behind the
ventilation controls inside the dash. I was unable to find the amp in that
location. It would be obvious if it were located where my Toyota man said it
would be. So, either the amp was there and the installer had removed it or
the truck never had one installed in the first place. If the latter was
true, then there must be some intermediate cable between the main harness
and the stereo as the Toyota dealer said does not exist. If the former were
true, then the installer would have gone to extra work (it wouldn't have
been in the way of the aftermarket system) and it was not returned to my
son, as it should have been. They did return his original stereo at the time
of installation of the aftermarket unit. Can anyone with some specific
Toyota information help? Is there a intermediate cable? I have pictures
that may help. Thanks.

There are 2 factory headunits, 1 type has an interanl amp the 2nd has an
external amp. The units with a \n internal amp have connections for the
factory 6 & 10 pin connectors. The units with an external amp, connect to
the amp by a 20 pin pigtail on the amp. The factory 6 & 10 pin connectors
plug into the amp.

If the back of yor son's headunit does not have a 6 pin& a 10 pin
connections, but instead has a 20 pin connection, it needs the mating
external amp.

The head unit actually has three recepticles on the back. I have three
connectors coming from the main harness.
Pictures are worth a thousand words.Paste these into your browser and you

I'm almost convinced that the external amp was employed. Which would mean
the installer removed the amp but did not return it. What recourse should I
expect from the installer (Lombards in California, should be reputable) if
that were the case?

That radio had an external amp, you can tell by the 20 pin connection on the
back. The 12pin connection on the radio is to connect an external cd
changer. The third connection on the radio (also 20pin) is for the steering
wheel controls. The connections you show in radio6.jpg and radio7.jpg are
the oem plugs that carry power, speaker connections etc and need to plug
into the external amp. The connector you show in radio5.jpg looks like the
connector for the steering wheel controls that plugs into the radio..

Thanks for sharing that information. The Toyota dealer was not as helpful. I
think the radio installer was very disingeuious, especially since we asked
for the return of the original equipment.
