I have placed diodes in the locations that are marked in red. Two door truck. I thought the diodes marked in blue were factory, but my alarm still goes off after 30 minutes. I guess I need to place another set of diodes near the BCM. Anyone have experience with this issue? Thanks for any help.

Your supposed to add the blue diodes too. The object is not only to isolate the pins from each other but from the BCM too. I personally have had no problems using the BLACK/ blue dome light supervision wire for door trigger instead, it's a lot easier....

Just don't shut the dome light off with the switch .....then you have NO door trigger.

I would imagine you mean hooking the door trigger wires up to the domelight supervision wire or do you mean totally disconnect the door trigger wires. I normally wouldnt ask a dumb question like that, but its cold outside right now.

You would use the positive door trigger to the BLACK/ blue, not using the negative trigger you have now...

Im having problems finding the wires. I think Im going to diode the BCM instead but I cannot find the damn thing. Anyone know where it is on the 2000 F150?

The BLACK/ lt. blue positive trigger is in the passeger kick panel. The individual triggers are at the BCM, which is part of the fuse box. They are hard to reach, it's easier to unbolt the BCM and pull it down as the wires are in the back up top.

Yeah, I finally found the sneaky thing. Got the diodes set and now I'm just sitting and waiting for that thing to go off again in my driveway. If it goes off this time, an RPG will pierce the windshield and take care of that siren once and for all.
