VSS/Reverse Light/Parking Brake Sensor

I am installing a F900BT in my 04 Ranger Tremor. As far as audio connections go I have found all the wires but I am not sure where a few wires are that need to be connected for the Navigation and DVD Player.

The wires I am looking for are:

Vehicle Speed Sensor
Reverse Signal
Parking Brake Sensor (assuming this will be on the back of the pedal?)

Any info on the location of the wires that I could tap for this would be greatly appreciated. If possible I would like to not have to run wires past the front dash for these (not to tail light or hood).

Thanks!

Parking break sensor is above the parking brake, just follow the break pedal up into the Dash, There should be a sensor there like what is on the brake pedal.

Speed Sensor,
Speed Sensor Input (Explorer Gray/Black at console)-

2003-back Ranger: Gray/Black at GEM
2004-on Ranger: Gray/Black at Smart Junction Box (brown connector) Passenger Kick panel I beleive
Here is the link to John's OHC wiring How-to

Reverse Signal I am assuming it is talking about the reverse light wire. I am unsure of this wire color but I would pop your tail light off and see what color it is. Then get under the dash and find that wire. but I am sure someone with a little more knowledge will chime in.

Thank you for such a fast and detailed response!!

Yes I am referring to the reverse light wire. If anyone knows off hand the color coding of it that would be great. Otherwise I guess I will end up pulling the tail light out.

Edit: I was looking at your CarDomain link and the links to the details on the mods bring up an error (CarDomain is having technical problems at the moment.) but looks like you did overhead console install. I am assuming you pulled that from a Explorer. Def looking to do that mod myself.

No problem good luck with the install, Ohh, I would advise using the red wire taps. I used the blue ones on my OHC install and 1 of them did not contact so I had to replace it with a red one.

Some systems require the switch (I know of a Jensen that does) The avic f900bt does not require a switch.

the12volt.com there is wiring diagrams and caraudioforums.com in the security section there is a web page for all units and how to bypass them. i have only bypassed a few for personal friends because it is against the law. reverse your probly going to have to go back to the light. are you going to be running a camera? if not then dont worry about that wire.

Manual says even if not using a reverse cam (which I plan to add on later) You still need to connect it so that the nav system can detect which direction the vehicle is moving.

Quote:
Violet/white (REVERSEGEAR SIGNAL INPUT)
This is connected so that the navigation system can detect
whether the vehicle is moving forwards or backwards.
Connect the violet/white lead to the lead whose voltage
changes when the shift lever is put in reverse. Unless
connected, the sensor may not detect your vehicle
travelling forward/backward properly, and thus the position
of your vehicle detected by the sensor may be misaligned
from the actual position.

When you use a rear view camera, please make
sure to connect this lead. Otherwise you cannot
switch to rear view camera picture.
