viper 5902 in 1999 ford explorer

I am installing a Viper 5902 in my 1999 Explorer XLT 4D and am thoroughly confused. I have installed systems before in the past but it has been years since. I have gotten several "wiring diagrams" from different placed on the web that have all varied which is kinda the reason I am confused. I have tried connecting everything to the best of my understanding but the only thing I can get the system to do is set off the "panic" and get the interior vehicle temp! So any help in the with this will be greatly appreciated!NExtelmike

A few thoughts :

Your Explorer requires a transponder bypass for the remote start to work.  What

bypass module did you use / install?

Look up DEI Tech Tip 1076 for the proper door pin wiring for the Viper alarm.

It would be a great help if you listed each of the Viper harnesses and the actual

connections to the Explorer.

As always, the wiring guides and just that, only guides.  It is necessary to

locate and verify each wire with a Digital Multi Meter prior to making anyconnections.

Soldering is fun!

Hello kreg357, I have used DEI's 555P Bypass Module I didnt really want to give up a key. This is how i have everything connected at the moment and it has me completely stumped. I know the Explorer has 2 stage unlocking but i dont really care about keeping that feature.

H3/2, H3/6, and H3/9 all to 12 volt constant.  Yellow Wire according to Bulldog.

You might have a 2nd accessory BLACK/ Light Green, if so connect H3/7 to it.  H3/3 to Gray / YELLOW.

Test and verify all wires with a digital MiltiMeter

What Mr Smoke says and...

H1/4 is not used for your application.  Make sure the Vipers Parking Light

Fuse/Jumper is in the (+) position.

You could set the Viper to control your Rear Defroster using the H2/16 output

and some option programming.  Here is the info from Omega :    Rear Defrost  Dark BLUE/ORANGE (-)     AT REAR WINDOW DEFOGGER SWITCH

Not sure if it's just a pulse or a latch.  Test to find out.

While the directions are a bit vague, here are the connections for your 555PW bypass :

The PATS transponder connector is about 8 inches down the steering column from the

ignition switch.  Look for a  white 4 Pin connector with WHITE/ Green at Pin 4 and Grey/Orange at Pin 3.

Thanks for all the help and taking the time to respond.. Thank you Kreg357 for the Bypass configuration I pretty much had that one figured out it was pretty easy. I have tried the configuration according to what Smokeman1 stated and according to the bulldog website and that configration does not work, when the battery is reconnected the brain goes haywire and tries to start the truck and wont stop until the power is completely disconnected. I also thought i had the OEM alarm disarm wire found but apparently not and i cant seem to find it there are several Drk GREEN/ Purple wire and none of them show any power when unlock is pressed.. so i am still where i was yesterday...I mean i cant even get the locks to work the light to light or flash nothing only the Temp in the truck and Panic work..... i am soooo frustrated...NExtelmike

That trying to remote start when power is first applied might be normal for a Viper.

Maybe a heavy-duty Viper installer can clarify this on a 5902.

*** Set Viper Flex Relay to ACC2.  Menu 3, Item 8, Option 2

To locate the correct Disarm wire ( and the Lock & Unlock wires ), use this method:

DMM set to 20V DC, Red lead to +12V constant, Black lead to suspect wire.  When thecorrect wire is pulsed, the DMM will go to +12V.  In the case of the Disarm wire, tryusing the key in the door to unlock and watch the DMM for the +12V pulse.  Might haveto use the passenger door cylinder or the Factory Remote.  Try to find the harnessas it comes into the kick panel from the door.  Just be glad you don't have a GEMmodule to deal with. 

Soldering is fun!

Okay.... soooo I have hooked H/3 harness as listed above and anytime the H3/9 is connected to constant 12V the starter engages and wont stop trying to start the truck, but none of the dash lights come on like the when you would have the key in the "on" or "run" position it just tries to start. Also now i can hear the door locks in the Brain "clicking" but nothing happens until the lock or unlock buttons are pressed on the door then the doors lock or unlock depending on the button pressed but it doesnt stop it just keeps going.. Thank you for the method to find the OEM alarm disarm wire i believe i have found it.. but still no parking light or lights flashing and i have also lost the communication to the remote all it says now is "out of range" and wont do anything. The remote displays a unshaded lock and every now and then will flash "valet" but i can't get the control button to respond to anything to (i guess) disable valet mode it just has a faint blue glow that is one steady...i know this isnt rocket science i have never had this much trouble before... Thank you again for taking the time to assist me i have posted in other forums and no one ever replies so thank you....NExtelmike

If it starts cranking right away, are you able to step on the brake to disengage the remote start action? Shouldn't start if the hood pin is installed and working properly.    Just asking not trying to be insulting, have you used a DMM to check and verify the wires at the ignition? 

Is the 5902 new or used?  Maybe a relay is stuck in the brain causing the cranking.

I have tried hitting the brake pedel after connecting H3/9 and it continues to crank the starter... no insult taken i have verified the Ignition wires.. the 5902 is brand new i was thinking the same thing about a relay being stuck in the brain but it only does it randomly meaning when it starts i unhooked H1/2 from 12V and waited a min or so and reconnected it and it had stopped but like 5 mins later out of no where it started again i had not touched anything as i was on the phone at the time..i will check out the link you provided... i have done couple of these in the past but its been a while but none have been this frustrating...NExtelmike
