2011 odyssey factory alarm disarm

I have a 2011 odyssey
I installed a remote starter and I was able to hook the lock wire to the factory alarm arm wire on the drivers door power window master switch (PINK). This works!
I thought that the unlock was in the same location pin 34 or 32 brown or white. They should receive a -- pulse? These do not work.

What wire do I connect the double negative pulse to to get the doors to unlock and the alarm to disarm?

DirectWire states

Factory Alarm Disarm     
brown (key unlock) and white (unlock detection)     
double -     
power window master switch, 37 pin plug, pins 34 and 32

Use both wires and diode isolate them.

I do not understand?

I have the direct wire information and I connected a - to the brown with no result?

For this vehicle, you have to use both the white and the brown wire and have the remote starter double pulse both wires at the same time to unlock.

There may be a couple of ways to do it (depending on the remote starter used). The best way (in my opinion) is to add two 1-amp diodes (like a 1n4001 or similar) to the end of the disarm wire, with the band of the diodes towards the disarm wire. The other ends of the diodes then go to each wire on the master switch (brown and white)and program your remote start for double pulse disarm.

I'll try to get a diagram posted if it's not too clear.

I will get 2 Diodes (I hope Radio Shack has them.

Just to be clear. The banded end should be closer to the remote starter?

I have a Viper 5900

Thanks for your help!

Radio Shack should definitely have them. I've purchased diodes there before and fairly cheap too ($2-$3 if that). You are correct, the banded end goes towards the remote start disarm wire. That should leave you with one open end of each diode (2 total) without the banded side. And that is what you connect (1 each) to the brown and white wires on the master lock switch. Once installed, every time you press unlock, the remote start will simultaneously send a double negative pulse to both wires and unlock your doors. Nice system by the way, it's the same one I use in my car. Just a side note, if you plan on using ignition controlled lock/unlock (one of the features on the DEI units), you may want to use the blue/green lock/unlock harness instead of the arm/disarm wires of the 5900.

You Rock, Thanks. I will install tomorrow and let you know the results.
Yes I am using the 3 pin Light Blue & Green wires for this!

I am concerned that this will not solve the issue (although I have Faith!)

I would expect that the - pulse would have unlocked the vehicle without disarming the alarm?

We will know tomorrow.
Thanks for your help!

OK I connected 2 diodes to the light blue unlock wire on the Viper 5900
with the bands on the diodes pointed at the 5900.
I connected the other 2 ends to what I believe are pins 34 & 32
On the connector the pink is 35 there is a white next to this wire and a smaller gauge brown 2 spaces over.
When I press lock on the viper the car locks and the alarm light on the dash flashes.
When I press unlock the doors do not unlock but the alarm is disarmed.
I connected only 1 diode to the small brown and verified that this is definitely the disarm wire.
Any suggestions?

Ok, awesome! You are definitely on the right track.

It sounds like the 5900 is still set to single pulse on the unlock function. You would have to program the unlock feature to send a double pulse. To confirm it's all working before you reprogram the option, (and with both wires connected), you can press the unlock button twice on the remote (within 3 seconds of each press) and it should unlock the doors as well as disarm the system. That way you know once you set the double pulse option, it will all be working.

Thank you! After programming the unit it works great

Great! I'm glad it all worked out. I knew you would do it.

It was my pleasure to help!! Enjoy it!!
