Viper 791xv install

1) It can be used as a secondary GWR output, or in pulse/latched mode, can be used to turn something on 10sec after remote start( rear Defrost, for example) 2)Yup... you can use channel 4, or even the trunk output for the window module... any thing that can be set up for validity (on as long as you hold the button) As far as the 508D is concerned, you will notice a loop at one end connecting the green and blue wires, and a loose green wire. Viper has multiplex capability on their sensor inputs, which is nice. You can have 2 sensors coming in on one port, and both will have full capability.... no need to diode isolate sensors from each other. Tie the green and blue together on the 508D, and connect to the loose green in the shock harness. You will be able to turn off each sensor separately from the remote, and each sensor will have it's own separate warn and full trigger responses. Kinda neat. 3) Nothingmuch, really. The only thing I have found annoying with DEI stuff can be playing "hide all these damn boxes" For example: Just did an 04 Trailblazer this morning with keyless. So, I got to hide 1)the brain 2) 555LW 3) 455G 4)The relay pack. PITA, but, that's the only complaint.... pretty minor. Everything else is straight forward on these things.... having a Bitwriter makes programming a breeze, obviously, but the menus aren't too bad to zip through with the valet switch an d the LED. Have Fun, enjoy the Starter Alarm! Gus Wherever I go, that is where I end up......

Cursed dyslexia strikes again..... yup. WHITE/ blueis a negative activation input. Can be used with a 556T for example to start at a given time of day, or a pushbutton switch for that one time the remote decides to lose it's mind, and you want to start the vehicle without a key. Wow... and it's only Thursday.... crap. Gus Wherever I go, that is where I end up......

I installed the 791xv on my 2000 Silverado last week. And you are right Gus with all the wires and the brain and the starter relay where do you to put the stuff at? I have question about mine. It took me three days because it was my first time installing a Viper. My question is that I get a check engine light on when I use the remote start. Check engine light stays on until I reset the pcm. Also when I take off the transmission is in third gear and will not come out, until I stop and turn the truck off and then restart with the key. There is a brown wire that I think, it is part of the ignition that I didn't hook up. I hook up the pink and the orange wire but did nothing to the brown wire (which is part of the factory wiring not the Viper). Was I suppose to hook up the brown wire to the Pink/White + wire (second ignition)? Because like I said that if I start the truck just using the key, its shift fine, but use the remote start its stuck in third gear. Any replys will be helpful because I'm installing another one on my 2002 Tahoe.   Thanks

Dohoo

Pink/white on the high current harness of the 791 HAS to go to the white second ignition wire at the column. Powers up part of the TCM, and a heater element in the tranny (from what I gathered onetime when I was looking at a service manual). Brown second accessory dosen't need to be powered up. The orange first accessory does. Playing "hide the stuff" is part of the allure of being a DEI installer.... and really ugly, 2 sizes too small, free t-shirts once in awhile .
