2008 Ford F-350: Crew Cab, Lariat, 4X4, 6.4L, short box
I'm trying to install a Ford alarm upgrade. Going by the instructions. I cannot find the color of wires they want me to use at the designated locations in the truck. This is a Ford alarm!

Are their any wiring diagrams available that may be up to date?

Does anyone know what color the dome light wire and door lock positive wires are?

Try the door pin for dome light. Installers seem to like to cheat, since the door lamp will come on when any door is opened, it is easier to use it instead of all of the diode isolating.

Lock should be Blu/grn and is a ground. Put your meter on this wire, you should have something near 12v on that wire. When you press the lock button it ground out leaving you with less than 1v.

 

Thanks, will give it a try.

 

Alarm installed but truck will not start with alarm module plugged in. I jumped across the terminals in the alarm wire harness, connecting the in and out for the starter kill and it starts. I was told that the starter kill feature can conflict with the PATS key. Is this true?

 

Not really. The pats is separate from the starter kill. Start kill interrupts the wire that runs from the key to the starter solenoid. My ford RS didn't use a relay and handled the start kill inside the brain. When the module didn't have const 12v, I couldn't start the engine. Just so this doesn't pull massive amounts of power, I believe it was hooked into the ign1 wire. When ign1 is energized, the starter kill was deactivated.

When you have an out board relay, it's done a little differently. I can help out more with those.

Sorry to bring an old thread back to life but I would like to add the factory alarm system to an 08 F350. Does anyone have these instructions handy?
