Well I did it tonight and I can say this I hate the back of my dash, here is the install procedure i used incase anyone is intrested Warning this was done on a 2005 SE Taurus sedan directions may be diffrent for others. I take no responbility for any damage. Make sure to cover all connections either with the crimp caps or shrink stuff
10k ohm resistor
The metra dash kit (of course)
Ford Din keys
Hex screw driver
torx screw driver
Remove the factory head unit and the cage that is supporing the back of the headunit
put this to one side for a min
Solder on 2 bits of wire to the resistor to create leads for what you are about to do
Using taps tap wire 3 Brown/Blue and wire 5 Red/Yellow on the factory radio harness
when looking at the connector with the clasp bit up pin 1 is on the top right side. Using the electrical tape wrap every bit of the resistor and taps so no metal is exposed. (Big warning you dont want this circuit grounding out as it may deploy airbags without warning) put the harness to one side for one min
Step 4 follow the install kits instructions to run the wires from the RCU
from the trunk to the dash and wire up your radios harness.
plug in the harnesses but leave it danging for a moment and start the car to make sure everything works.
Step 6 Shove everything back in the dash including the aftermaket radio
Step 7 Enjoy!!1[/b]
