am installing viper 790xv, the disarm wire output shows (-) on the viper reference and it say to use a relay. is the accord a neg disarm or positive disarm? if it is neg disarm for the accord, do i need a relay.

To disarm factory security, find the blue wire and supply it with a negative pulse : On the EX the wire is located at the drivers power window switch, on the LX the wire is at the keyless/security unit which is attached to the drivers underdash panel - use a relay as instructed

I usually just set up my unit to unlock the doors before remote start, and then re-lock them right afterward; this is easier than going into the door.

use a DMM to test and see if that wire gets a negative pulse when you disarm the factory alarm

am sorry to ask you but what is DMM test, am not much of a electronic wiz. i got every to work so far but the arm goes off when i remote start. this is probably the last wire i need

If you're just tying into wires at random, you shouldn't be installing. A DMM (digital multi-meter) will come with basic instructions on how to use it, or you can probably find more information by searching around this site.

The best way to find the wire is to just go into the driver door. Look for where the key cylinder is and find the wires coming from there. When you turn the key to unlock the door the wire will show negative.

the wire is blue at the drivers power window switch ( thre is usally only one blue) use the light green \ black wire out of your remote starter. this will disarm the factory alarm.

how can i test this wire. does this wire arm after you arm your alarm (lock). on the power window switch have two blue, blue solid and blue/white.

the alarm will arm when you lock the car and will disarm when you unlock, but to disarm without unlocking use the blue wire. To test use your multimeter set it for 20V dc. gound the black clip the probe the (BLUE) wire at the switch. it will show 12v. then turn key in the lock cylinder it will read almost 0, but then again there is only one blue wire. good luck. TEST WIRES.ALSO is this a Honda Accord EX or LX? LX models can only be armed and disarm with the factory remote only.

I may be missing somthing here, but where does the blue wire in the door go to? My question is, it has to go into the drivers kickpanel, and to somewhere, security module (im assuming).. Why do you have to spend the extra time pulling door panel and routing wire?? I just did one of these, and found one blue wire coming out of the door, I probed it, and did not find the readings I expected. So I wired the remote start to unlock doors first on remote start request, and then to lock doors after startup. The Accord I did today was a 2002 SE.

My best guess is that the blue wire comes from the door key cylinder and sends a ground to the power window switch. And then, the power window switch also functions as a sort of computer......... it sends data down some other wire to tell the car that it's time to disarm. We can either get the wire at 12 volts negative inside the door, or make/invent/buy a piece that'll make data to tell the car what to do........and probably no one's going to pay for a databus module just to perform that one little function, which isn't entirely necessary anyway.

I agree with Chris, and also is not that bad pulling the door panel off a Honda Accord anyway.

Regardless of what it does at the switch, it has to send a signal to the security module, or body contol module (Whichever controls security).. So which wire does it?? for cost reasons, Honda would not put any kind of module in the door that deals with security, thus the signal sent out would not be data, it would be a ground pulse. On monday, I will look at a complete wiring diagram of that security system, including the door lock. There has to be an awnser to this. Its not that the door panel is hard, or time consuming to remove... There just has to be a wire coming out from the door... And I cant stop thinking about it!!! ------------- Hak

i got the wire. i saw the wire coming from the key hole but i didnt know how to test it. it's the black wire coming from the key hole side plug. first time, i tried using arm and disarm both from the remote and switch to test it, nothing shown. what i notice is that the arm is passive and can only control by the key like someone mentioned above.

Ok, update... There is a multiplex unit inside the door... So you have to tap into the blue wire in the door!!! WHAT A BUMMER> I would suggest doing what I did.. Unlock doors first on remote start request. ------------- Hak

well i got the the wire tested and constantly ground it. i know it beat the whole purpose of immobilizer but does this mess up anything inside the system?

hey profuse007 let us know if the accord is a lx or ex,and then we go from there,is not that hard.
