so any one know where the vss is and is there a possability that i can uatlise the factory amp

I can't find anything on the 2001, however on the 2000 it's listed as VSS Wire Green/Orange Pin 15 at BCM. They might be the same so you could try that. I'd test it first prior to hooking up to it to make sure.

yea im not sure but i called my buddie over at toyota and hes going to printup a wiring digram for me because i havce searched everywhere and cant find shit about it

For the 2002 and 2003 I found:

green/orange at the instrument cluster in the brn plug.

is it preety easy to get out the interment cluster and where is it opn there ?

I'm not sure how easy it is to get the cluster out. I just posted the wiring info that I found online. Sorry.

I too don't know and was posting info I found on line also. Tapping into the wire off the BCM module might be easier to access than pulling the cluster. What I'd suggest is you buy a manual such as a Chiltons or Hayes for your vehicle. This should give you info on the location of your BCM and/or pulling the cluster, which ever route you choose to go. If you're still unsure you might be better off taking to a car stereo install shop and having them do it for you. That way you'll know it's hooked up correctly, and I wouldn't think would cost very much.

i went to some of the shops around here and to put in the avic n1 it was going to be around 3 hunfred dollars to put it in so not cheap thats forsure but that you for the advise just think im going to take it to my budy that works at toyota and have him look for it for me but thanks anyway
