Ok so I just installed my z1 in my 2000 Toyota Tacoma but I did not hook up the VSS wire just yet since I am unsure what wire to use. Does anyone know the location and color of the wire? According to the "rostra" website that is linked from this forum it is the green/orange wire located in number 8 OR 9 OF 22 PIN CONN.OR POSITION 12 OF 28 PIN CONN.OF ECM. Does this mean that I could use either one? Can someone confirm that this is the right wire? Thanks. BTW this unit kicks A$$!!! It is a newer unit and I grounded the two wires for the bypass. Works great!!!

VSS is a green wire with an orange stripe at the ECM, behind the glove box.

Thanks!

U got it....!

It didn't work. I'm guessing that it wasn't the right wire. The head unit read a signal but whenI would come to a stop or press in the clutch the rpms would drop and it would idle very bad and almost stall. I disconnected it and the truck ran fine. Strange. So I still need the right wire for the vss. Thanks.

You sure you got the right one. If I remember correctly there is more than one green/orange wire at the ecm.

I checked every plug on the ecu and could not find another green with orange wire. Do you know if there is another location to get the signal like behind the gauge cluster? Also my truck is lifted and therefore the signal that my speedo and odo get is off. Will this effect the vss connection to the z1 or does it learn the signal based on the gps speed? Thanks for the responses guys!

I also see that you called it the ecm vs. ecu. I assume there is a difference. That is probably why I am all jacked up. I was tapping the wire off the ecu. Oooops! So when I can get some light I will try to see if I can find the ecm.

I had to hook up a cruise control on my Tacoma and the wire is right behind the glove box. I can't remember the color though.

I have a Tacoma but I did not install my AVIC in that vehicle. I do not know the answers to your questions or I would help you out. I was just wondering if you could post some pics of it installed in a tacoma. I bet its sweet.

sure as soon as i put my dash back together i will snap some pics.

Did you ever find that wire? I'm currently installing a D2 in my 99 Tacoma, and am also having a bit of trouble finding the correct wire. If anyone has a photo of the correct harness to use behind the glove box, that would be great.
