I am installing an alarm into a F150 Custom, and looking up the alarm diagram for my truck, i found that none of the wires match. I am trying to find the Constant 12V, (which i found 2 wires that ran 12V with my DMM), and the starter wire. Please help.

Notes:
*1 ESSENTIAL to use driver's switch when testing for switch and motor sides. *2 On diesel trucks use WHITE/ black at the alternator for tach. Also the wait to start wire is BLACK/ pink (-) at the warning light on the dash or the glow plug controller on the center rear of the engine.

-does any of those wire match at all?
-finding wires at the iginition harness is really easy. look at the thick guage wire.
starter: 12volt (+) only when crank
ignition/acc: 12 volt(+) when key turn once-acc. 12volt when key turn twice-ignition
thats it!!!!

No, none of the wires match. I printed up the wiring diagram yesterday from this web site and looked at the wiring harness in the truck, and nothing matched. But, I will try that today. Thanks for the help.
