Car: 2007 Ford Edge
Alarm: Viper 5901
Problem: Unit doesn't respond to anything. Also pressing the Valet button or remotes do not do anything and LED doesn't respond either.

I'm in the process of installing the unit taking small steps and verifying things as I go. The only thing I've connected on the main harness is the power (Red), ground (Black) and parking lights (White, through a relay). When I tested it it worked fine and proceeded to install part of the remote start harness. The only wires on the remote harness I installed are Ignition 1 (pink) and Starter (Violet & Green). Now it seems that the unit has locked up and possibly failed.
With everything unplugged (with or without the antenna/Valet button connected) as soon as I connect the main harness (not the remote start or accessories harness) the parking lights come on and the main unit doesn't respond to anything.
On a side note when I first received the system I tried charging the remote and it wouldn't charge. After connecting the remote to three different chargers it finally started charging and will now charge on the factory charger.

Has anyone seen anything like this before?

Check if you've connected your pink ignition wire to constant 12volt source. The remote charging issue happens with me sometime, i just re-plug it in the same charger a few times an it works fine after, i dunno why.

I can disconnect the remote start harness and still have the same results.

why are you even attempting to press buttons and such with only 3 wires hooked up?

I was testing the parking lights to make sure they flashed and then going to move on to make sure everything worked as I connected it. It makes trouble shooting easier. If something is incorrect I didn't want to continue until that problem was resolved.

How did you wire the relay to the parking lights? I see where the diagram states a relay is required. I was wondering if it is wired like a Windstar isolation setup. https://www.bulldogsecurity.com/diagrams/extrainfo/diagrams/28464_WINDSTAR_FREESTAR%20WINDSTAR%20PARKING%20LIGHT%20DIAGRAM.pdf

you need more than 3 wires.

ign, acc, ground, constant 12v, door trigger,parking lights just to program remotes,
