One more question.

Does this wire only activate once you press the unlock on the key fob twice?

Yes if you have priority unlocking; that is you have to activate the fob twice to open all bar the driver's door, it's your car, you tell me!

Yep. Thats how it works. I'll be installing the alarm this weekend. I'll report back once done. Thanks so much for the info.

OK. So i was able to identify all the wires for lock and unlock. I can't tell what voltage level they are since my old fluke hand held DMM isn't fast enough to take the pulse reading.

I'm wondering if I do need to add relays here to boost the signal?

I guess i will try it first and see if it works.

One strange thing I noticed is that when I hit unlock the lock wire has about 500mv on its line. not sure if that will be a problem or not.

Hey man. Thanks for your help. I was able to get this installed and working today. I tapped into all the wires right at the fuse box right behind the glove box and just ran a power wire directly from the battery as I didn't feel comfy grabbing power from inside the car circuits.

When unlocking/ disarming am getting .5v in the lock wire ( J05 pin AP ) this seems to be causing issues. My fiancee used the car today and she unlocked it ( it chirped to confirm unlock ) went to open the door and the alarm went off. I can't reproduce this so I am not sure what to think.

Should I install the door lock pulse adapter on page 17 as good meaure?
