2003 wiring harness

[pb4sc]

Does anyone know which stereo wiring harness will work for the 2003 Tundra? I got one from American International (twh-950) but it doesn`t match. Is the 2003 stereo plugs different?
Any help would be appreciated. I hate to cut the wires.


Thanks,

What doesn't match about it?

On the factory stereo there are 2 receptacles. one has 20 pins row 1 and 10 are large pins row 2-9 are small. The other has 20 small pins. The twh-950 has 2 receptacles also, but the pins are all large, and there is only ten on one and the other has 4 large pins. Also both twh-950 receptacles are too small. When I tried to attach the twh-950 to the female receptacle that I pulled from the back of the stereo, they dont fit. Thanks for your help

So you are saying that the twh-950 will not plug into the Factory HU is that correct?

If so, it is not supposed to. The twh-950 is designed to allow an aftermarket HU to interface to the Toyota wiring harness.

On a Tundra the wiring harness (2 connectors, a 6P and a 10P plug into the amp, the amp has a 20P pigtail that connects to the OEM HU. The OEM HU also has a connector for adding an external CD deck.

Hope this helps

pb4sc,
I am guessing that you have the cd and cassette stereo in your truck. That radio does have a factory amp included with the headunit. You need to remove the amp and get to the wires on the factory amp and use the plug on the amp to plug in you new headunit. Hope this helps!
