By reverse signal I mean the signal used to drive the reverse (back-up) lights. Can it be accessed from somewhere in the front of the vehicle?

Hi David,

I wanted to install a GPS in my 2000 Toyota Echo 2D sedan (manual). I was unable to locate the reverse signal. Is it located in the ECM? If yes, how do I identify it?

Thanks,
Vineet
Answer -
Reverse signal?  As in the reverse lights or am I mistaken?  Are you installing a DIN GPS system?
Answer -
Hmm..  I'm a bit curious to what GPS device you have but anyways, the reverse signal you are looking for can be found behing the guage cluster.  It's a connector behind the cluster that contains the signal I believe you are looking for.  Outside of that, I don't think so, especially for a 2000 Echo since Toyota went neat by that time, hiding wires to show a more clean look to it's auto wiring:)

Answer
I must be crazy.. The switch you are looking for will probably be the "park/neutral" switch on the tranny.  The wiring diagram I uploaded for you is avaiable here.  It's in MSWord '03.
