06 f150 door trigger

Hello I searched all i could with no results. I am installing a code alarm, alarm/starter in a 2006 Ford F150. I have found the door trigger wires in the drivers side sills however i see multiple of the same color wire and when I test with a voltmeter i do not get any voltage. I was planning on isolating each wire but i am unable to confirm which wires are correct and if they are positive or negative triggers. Thanks for your help.

DONT hook up any wire if you cant confirm that it is the door pin. i did one of these and did the same thing you are doing. i couldn't find the doorpin so i just used the wire that i was "sure" of without testing it and it turned out to be something dealing with the fuel system. after installing the truck would run for a minute and then quit and wouldn't really run far. it took a trip to the dealership to get it fixed but luckily i had done the owners' friend's car the day before and he knew people at the dealership that took care of it for me. LUCKY
