Printer Friendly Forum Posts - viper 791xv and dei 530t

on the 530t. the orange wire should b connected to a wire that is grounded when armed, what wire is this on the viper 791xv.

i was thinking the factory rearm but the manual says it will also send a - pulse when then remote start is shut down. does that mean it will close the windows when i remote start the car and push the brake?

there is an orange wire in the main harnes use that wire

primary harness (H1) 12-pin connector

how own your mind, control your life.
MECP certified. always use a DMM

Use the Orange Ground When Armed wire from the main harness, but be sure to go through the programming menu to 3-12 (I think) and de-activate Anti-Grind so that your windows will not roll up every time you engage remote start. The Ground When Armed output also feeds the starter kill relay, which is how Anti-Grind works. posted_image

I have mine set to engage everytime i remote start. Why wouldn't you want the windows up while remote starting? I usually remote start to cool in the summer or heat in the winter. I want my windows up during both of those occasions.

Well it's really a matter of preference. A lot of the time I drive with the windows down, and if I make a quick stop, like a convenience store or the mailbox, and either need my keys or don't want to leave them in the car, but want to leave the windows down while it's running then with the Anti-Grind disabled it will do so. But like I said, six one way, half a dozen the other. My main intent was to make sure that fpcelica was aware of this side effect of leaving Anti-Grind enabled.

Yeah I understand what your saying. I think keeping the Anti-grind would be a good idea though. I didn't bother with it when I installed mine way back when and I've probably accidentally regrinded my starter a half a dozen times in the 4 years I've owned it. Sounds dumb on my part but that feature would have prevented that if I took the time to wire it up. You just get sidetracked sometimes and cringe when you hear that damn noise. LOL

is it possilbe to have both the anti grind and the windows go up when armed but not have them go up during remote start. maybe with a relay or maybe using a different trigger that is ground when armed ? on a 3wire(-) does the lock wire put out a 200Ma? wouldnt that work?

isnt it kinda dumb that, the ground when armed wire isnt even really used on the 791xv for the antigrind

Actually the Ground When Armed wire is used for Anti-Grind, through the ribbon cable that connects the 791XV to the XCRS relay satellite. When the remote start process is engaged, the orange wire on the ribbon cable receives a ground, thus causing the internal Starter Kill relay to interrupt the PURPLE and GREEN starter wires.

does turning of antigrind turn off starterkill also? if not then what i was thinking is take the H3/1(blue/white), the wire that turns oin the rear defogger, and tapping it into the Remote start primary harness wire #7 the antigrind/grnd when armed, then turning off the antigrind on the system. wouldnt that still turnon the antigrind relay?

if turning off the antigrind feature also turns off the start kill then totally disconnect the ORANGE / black wire in the RS harness and connect both the H3/1 wire and the orange H1/1 wire to the relay side of the orange black wire on the RS harness. wouldnt that also give you both the the features of antigrind/ and windows up only on arm and not remote start?

No, the Anti-Grind function is an internal control that sends out the Ground When Armed signal when the remote start / takeover is engaged. If disabled, then Ground When Armed will ONLY be Ground When Armed, and the Starter Kill will function properly, as well as make your windows go up when the vehicle is armed. You can also install a switch in between the alarm and window module to interrupt the Ground When Armed wire if you would like the option to leave the windows down wjile armed, or if you have an extra channel, a relay to interrupt it with a latched input from Channel Four or Five, though that's a pretty big waste of a channel.

so would this plan work ?

Yes, you could connect a status output wire to the Ground When Armed input wire at the relay satellite to activate your own Anti-Grind without affecting the main Ground When Armed function. BUT, you will need to leave it connected to preserve the Starter Kill feature AND diode-isolate that connection by cutting the Ground When Armed input to the relay satellite, instaling a diode with the cathode (striped end) facing the alarm brain and connecting your status output on the relay satellite side of the diode, otherwise the ground will backfeed and trigger the main Ground When Armed circuit or worse...

can i get this diode at radioshack and which one am i suppose to get? and where can i get the regular sized relays?

Regular sized relays SHOULD be available at Radio Shack, as well as the diodes, which can be as small as 1 amp. The type I use for this type of application are just small enough to fit INSIDE the end of a RED (18-22 ga.) butt connector.
