connections for kenwood nav?

i got a 2001 toyota tacoma and i was wondering if someone had a wire diagram for it.

need the vehicle speed sensor wire and location.

and whats the purpose of the reverse wire?

btw its a kenwood kna-dv3100

thanks

i tore that truck all to pieces last nite and couldnt find anything. is the ecm up there kinda behind the airbag? with about 4 or 5 plugs in it?

and what is the speed sense wire for also?

thanks

ok i found the vss wire, its is a green wire in the ecm.

now where would i find the reverse wire other than at the tail lights. figure it would have been in the console area but i didnt find it.

and what is the purpose of it for the nav, is it necesary?

the vss wire i found but a multi meter, it fluctuates with spped, while still has nothing, start moving it reads ac voltage.

i'll look again tomorrw for the reverse wire, just had wisdom teeth pulled today so im a little out if it.

any clues to what color to look for for reverse wire? nad that is the wire for the back up light? right? LOL

well the vss wire wasnt right, but it did get my air bag light flashing, but i  did find the right one. LOL

anybody know how to get the light off now?

thanks
