I wanted to resurrect this thread because a couple of people where asking about hooking up the rear door popper so it releases with an after market alarm. As you can see from above, Raque Thomas figured out how to wire the door popper in so that the stock Isuzu key fob would release it. The link to his wiring diagram is broken, so I used a printed version of the original thread that I had lying around and I CADded it up so everyone could have it if they would like to do this mod.
I started this mod, but my wiring behind the dash is a little screwy thanks to the PO, so this is half done right now. It's wired now so that both doors unlock with one press of the key fob button, but I haven't wired the new relay in yet so that the second press opens the rear door. I'll get back to it soon though.
Here's how it should work, according to Raque:
"When wired as shown, the door panel unlock switches will open the trunk ONLY if the key is off or out of the vehicle. I like this feature because I can open either door and just hit the switch to pop the trunk.
If the key is in the run position, the door panel switches still operate the door locks but NOT the trunk. The only thing that will open the trunk while the car is running is the switch in the glove box.
So, car off - second press on the remote, or door panel switches unlock the trunk. Car on - glove box switch only."
Enjoy.
