2009 Toyota Corolla, Stereo Wiring

Can some one help me identify which wires are for what on a toyota corolla 2009 ? There 4 harness with the some with the same colors

Welcome. In the words of another member, "What are you trying to do?"

What kind of information are you trying to find (stereo, alarm, etc.)? Is this for a key start, or a push button start? Do you have a multimeter and know how to use it? Keep in mind that any information you find should only be used as a guide until you have verified with a meter.

If you haven't read this thread, I would highly recommend it first. It pertains to stereo, but the detailed process explains how to verify wiring with a meter:

My ex once told me I have a perfect face for radio.

I'm trying to install an after market stereo.The harness I bought doesn't fit the after market stereo .So I don't know which wire colors coming from the car belong to speakers or illuminations. I found this diagram what does the TLMT stand for ?

Do not cut the harness off of your car. If you have not, and that is an exact diagram of the back of your factory radio, purchase a Metra 70-1761 and call it a day.

I already cut wires.

I have to guess that it is the Smart Key version.

If so

Thank you but I don't have a smart key corolla.I actually have toyota corolla 2009 LE
Can you please help me

I connected the factory radio harness back to the wires from car the once I cut off but now I think dimmer light on the factory radio turns on and off on its own when the head lights are on .I ended up putting the factory radio back on till I figure out the radio installment kit .Once again the dimmer lights are turning off and on on the radio .Does that mean there's a shortage .Please help

Go purchase a metra 70-1761 wiring harness. If your new radio does not have an illumination wire (Orange-White) then no need to fix your illumination issue. If it does have an illumination wire, connect it and see how the new radio reacts. When you turn the lights on the radio should dim a bit.

OK , what will cause the climate control and shift light not to work ?When I turn on the head lights The Illumination lights on the factory radio don't turn on ? How can fix this ? Can you walk threw the process if I give my email then I can give u my number

Hello , I've installed the after market stereo but now my panel fuse keeps blowing .This must mean I have a short ? I solder the 5 wires I clipped off and on the other harness I had I trimmed those and soldered them to the harness of the stereo

If you unplug the new radio does it still blow the panel fuse?

If it does not blow the fuse with the radio unplugged, you may have the green wire of the vehicle connected to the wrong place. Cut it free and insulate it.

Found the problem my Illuminati was plugged into a ground wire .Yes when I would plug in the second harness it will blow out .Thank you for your help
