Does anyone have any clue where I can find the speed wire and reverse wire in a 2003 Tahoe? Or any general tips as to how to find them.

Also, I'm sure this has been covered before but I might as well ask, does anyone have a link explaining how to bypass the video in motion block on it?

Thanks all!

the easiest way to get the reverse wire is take the wire all the way back to your tail light assembly and hook it up to the reverse light (positive).
as for the speed wire, it would be on the back of your cluster most likely. on my rex, it was on the ecu.

video bypass is a solder job.

AVIC-N2 lockout bypass: Underneath the MAIN unit (not the hideaway) is a small
silver sticker, peel this back. There are two contacts with the label "R197".
Drop a bit of solder between these to connect them. Also, you must ground the
Parking Brake wire.


AVIC-D1 lockout bypass: Find an extra Pioneer wire harness, and pull one of the
wires out. Or, if you do not use the A.ANT lead, pull that out of the harness.
In the AVIC-D1 harness, there is one open spot on the connector
(next to the ground wire). Put the wire into the open spot on the connector,
connect the other side to ground, then re-connect the plug to the AVIC-D1.
Also, you must ground the Parking Brake wire
(or connect to a toggle switch if you feel the need).

The solder job described voids your warranty, and all AVIC units go back to Pioneer for repair from what I remember.

juan is correct. it does void your warranty. however if you are good with a solder gun, and even better with a desolder gun..........:D
and as for the them going back to pioneer, that is also correct, nav pieces can only go to the pioneer navigation service centers, and there is only 2 of those.

Reverse light is light green on the black plug on the BCM.

The VSS wire is the green/white wire on the green plug on the PCM, which is under the hood, top left corner. You should be able to catch this wire behind the instrument cluster, as well.
