I have posted this on some other toyota related sites, but haven't really gotten the kinds of answers I need, so I thought I would try here and see if I get any better results.
I recently installed the Pioneer AVIC-Z1 navigation unit in my 2004 Tacoma Double Cab. I haven't done a stereo install since my high school days and this took me most of my turkey holiday .
I have everything connected except 3 wires. Two of the wires (speed & reverse) aren't strictly necessary for operation of the unit, but they make the nav more accurate in cases where it cannot get a good satellite signal (underground, etc). The last wire (parking break) is necessary for most of the nav & configuration functions to be operational.
Here are the wires I need to find out where they go:
Speed Signal Input (pink wire)
Reverse Gear Signal Input (violet/white wire)
Parking Break - Power supply side (light green wire)
I need diagrams, pictures, or very very good descriptions of where I can find the connections I need to make. If you could help me, I would really appreciate it.
