Your aftermarket will have one of three keyless entry outputs if it does not have internal relays: positive, negative or reversing polarity. In order to tell you exactly how to do it, I'd need to know what system you have. Basically, the idea is to split the unlock output into two circuits: one positive to connect to the unlock switch wire and one negative for the factory disarm. It would be best to isolate the two circuits with realys.
Za?

I've got the Viper 971X alarm....... I just figured it would be easier to remove the factory alarm... or disable it... rather then messing with the aftermarket AND the factory.

Isn't that an alarm and remote starter combo? If so, it probably already has a factory disarm output that provides a negative pulse upon pressing unlock on the transmitter or pressing the start button. That'* even easier. That particular output wire should simply connect to the LT GRN wire in the drivers door, jamb boot or left kick panel.

I emailed a Viper manual to Andy once upon a time... I'm wondering if it was for the same model. I'll have to get it from him cause I deleted the copy I had. Do you happen to have the installation instructions? I also remember someone else posting pics of the wiring diagram from a Viper system. I'll have to try to find it.

First, lets make sure of the model number. Is it a 971x or 791x? This thread http://www.bonnevilleclub.com/forum/...ic.php?t=23290 shows the wiring diagram for the Viper 791x. In the pics of the manual, it shows a LT GRN/BLK wire (H2-1) that is a factory disarm wire. This needs to be connected to the car'* LT GRN wire as described above. That should solve your problem.

I don't think most people worry about a factory alarm when stealing cars. Not that factory alarms are complicated either, or that Bonnies are exactly a "Hot Ticket" or high value car.

randman1 the cars at the mechanic for a week or so.....
I'll take a look when it gets back.

As for the alarm/starter... I believe it'* the 971.... it'* the highest one Viper sold last year.

Models numbers do change quickly in that industry.

I looked on DEI'* website and 791XV seems to be the top-of-the-line model. I just wanted to make sure that I was looking at the right wiring diagram.

Hey all,

First off.... sorry for digging up this nearly 2 year old thread.... but it'* still unresolved.

I've checked the wiring, and it seems proper.
The issue with both the cars is that the factory alarm arms if any door is open when the the car locks. So if I'm walking away from the car, thinking that all doors are closed, and a passanger still has their door open when I press lock.... damn... the next time I open the door the factory alarm will go off.

The factory manual says to turn off the alarm, to open the front doors with a key, or use the factory remote.
I've tried on both cars, both doors... using the key to unlock the doors does NOT shut off the alarm. I keep the factory remote in the 91 just incase I accidently lock the doors and one is still open.

The issue with the 97 is that it never came with keyless entry, thus no factory fob... doh. That means the only way to turn the alarm off, once it'* going is to disconnect the battery. :?

That'* why I really want to remove/disable the factory alarms in both the cars.
Does anyone know how?

They are so integrated I'd say the best bet is sell. Sorry...but they have wires going to everything.
