Can anyone please get me a copy of this document.
I do not have access to the DEI website.
Thanks!

Since you did not post the exact make and model of your vehicle I will post referencing a 2001 F150.
The GEM wakes up when it sees the door open so for your aftermarket system to work you need to pulse the door trigger wire for the GEM to wake up. Set your unit to double pulse it's unlock output and use diodes to isolate (stripe facing the your unit). Hook your unlock output to the driver's door ajar wire (BLACK / YELLOW) as well as the unlock wire (pink/green). If your vehicle has a factory alarm you need to pulse the factory disarm wire with this output too (dark GREEN/ purple) as well as using the factory alarm disarm output on the same wire.
I install mainly DEI products that have the ribbon cable running to the external relay pack. I actually cheat when I do one of these trucks. I run the unlock output from the system to the pink wire in the ribbon cable in addition to the door unlock wire in the vehicle. The pink wire in the ribbon is the wire that turns on the ignition relay. Setting the unit to double pulse unlock the first pulse will energize the ignition during the pulse which wakes up the GEM. This will however also energize the ignition every you press unlock for the duration of the door lock pulse.
Some trucks do not have the GEM and do not need to have this interfacing done. To test for the GEM open the driver's door, roll down the window, press lock on the door and shut the door. Wait 2 minutes then reach in the window and press unlock at the door switch, if the doors unlock you do not have to worry about the GEM interfacing. You would test for the factory alarm in the same manner except instead of pushing unlock, open the door using the inside door handle...if the horn does not beep you do not have a factory alarm.
Installer, IT support, and FFL. I need less hobbies.

Thank you.
The vehicle is a 99 Ford Windstar but your f150 example is close enough.

Sorry, you can NOT post a reply.
