Resistor needs to be between the red wire and the diodes in your pic.The yellow wire needs to be hooked to the diodes. The resistor is supposed to limit the 12v input from the red wire into the existing wiring. As you have it wired now you are putting full 12 into vehicle so you can't get to zero ie ground!Door trigger, 2005 Ford F-150 - Page 2 -- posted image.

ok that did not work either the doors are negative trigger the viper system does not detect the doors again with the way the diaods are placed the only way the door are detected placing the diaod block lines toward the truck wire not toward the the green viper wire

Have a question if by ohms law e=I.r 10.10000=.001vdc. If I were to turn the diode block trwrd the viper system and the voltage being in the hundreds of a single volt would that hurt the BCM

Been awhile since doing a Ford alarm install. Looked it up and Yup your right diodes are backwards, everything else should be right.

OK so to be sure were on the same page I need to turn the diodes around and let that hundredth of a volt go into the BCM I am trying to avoid buying a new BCM if you know what I mean

That's why such a high resistor on the (+)12v so the amperage is minimal as to not damage anything. It's amperage that is the killer in 12v systems.Door trigger, 2005 Ford F-150 - Page 2 -- posted image.
This is the traditional way but the second set of diodes cause the doom light and RAP shutdown to stop working. Deleting the second set of inline Diodes between BCM and door triggers and adding the !@v with resistor elininates this problem.

Ok that's what I was thinking too but I just wanted the second ok I work with AC voltage bit not DC ok I'm working at the moment I'll keep you posted
