Viper 5002, 2005 F250, Secondary Doors Unlock

As some of my old posts indicated, I had trouble with my alarm system. Well, I managed to find a brand new in box system and now need help enabling features the original installer did not enable. One of these features is my secondary unlock feature. I now have the 'auxiliary wiring harness' which I did not before. However, i Have no idea how the H2/1 needs to be hooked up. Can someone point me in the right direction? As installed, it's 'all or nothing' when unlocking. Thanks!!

I have this post here:

I understand this post, but I am not clear where to find the BCM Unlock wire in which to wire that.

Took a bit of reading but he’s basically saying to remove the currently connected 1st alarm unlock wire from the trucks unlock wire. Then wire the alarms 2nd unlock output to that same truck unlock wire. Then you would wire the alarm’s first unlock wire that you disconnected and wire it to the driver door motor circuit that he posted on the last page of the 2016 thread.

Thank you. I think I got it.

OK, so the 'second unlock' is basically going to unlock ALL of them, even though the driver door would be unlocked already with the first push. So the first button sends the unlock signal to the driver door, and the second unlock sends the unlock signal to ALL doors, which means the drivers door gets hit with two unlock signals when we are done. Is this the typical way to doing it?

I still have a problem. I got my new alarm brain installed. However, I have a wire that is not hooked up that I found.

Found two wires disconnected. No idea where they go as they have connectors on them so they should have mating connectors.

DOOR LOCK HARNESS:
GREEN/BLACK Lock #30 Common (Output) ------> Hooked up to a White wire with red tracer in my drivers kick panel
BLUE/BLACK UNLOCK #30 Common (Output) ------> Hooked up on the wire that is Black with white tracer in the kick panel


MAIN HARNESS
GREEN (-) Door Trigger Input, Zone 3 -----> ???? This wire has a connector but its just loose in the door. No idea where this should go. It doesn't look like it was ever hooked up. SHould it be? If so, where?


Can someone shed light on where this should go?

Also, I have a bitwriter, and I have saved my OLD configuration, but I cannot get it to program my new alarm (identical brain). I'd also like to program the old remote to the new brain. How do I copy settings?

Are you wired into the GEM system to wake up the system before attempting unlock? I think your truck goes to sleep after 5 minutes and needs to be woken before unlock will work from an aftermarket system.

Also, when I look at note #2 on the following vehicle wiring diagram it mentions that the unlock wire is found at the harness coming in through the door jam. Maybe the wire in the kick is only for all other doors. Just a thought. I’m not sure. Maybe someone else may know better.

How did you verify the unlock output on the new brain? Did you test for a negative pulse at the end of the wire? Try testing the wire right out of the connector where it plugs into the brain. If it works there then perhaps you have a break in the wire between the brain and the other end of the wire where your connection was made.

FYI...everything locks and unlocks on the new brain. The only question I have now is where this green wire goes:

MAIN HARNESS
GREEN (-) Door Trigger Input, Zone 3 -----> ???? This wire has a connector but its just loose in the door. No idea where this should go. It doesn't look like it was ever hooked up. SHould it be? If so, where?


The wire appears to not be used, although the original installers put a connector on it. Should this be hooked up?

ON SECOND THOUGHT...

That green wire shouldn't be hooked up at all. My (+) DOOR TRIGGER INPUT and OUTPUT OF DOME SUPERVISION RELAY #30 are both hooked into the BLACK/BLUE wire in my kickpanel which I assume is the dome light. So....the green wire doesn't even get used on this install.

Sounds like you’ve got it all figured out. Good job. Enjoy.

Note quite. I wanted to 'copy' my old settings from the old brain to the new brain using my BitWriter. However, It does not allow me to copy. When I load the file, it seems to take, but do I have to go through each menu item and 'write' it to the system? When I try that, I get an error about 'no remote'. Is that because I have not programmed my OLD remotes to the NEW system? What do I need to do to copy all the settings?
