the heavy gauge harness did need two connections to constant 12v - when i get the defrost and second lock wires corrected, i will post the updated connections

Second lock wire...? What is this for...?

the second unlock is also called progressive unlocking - the first press of the unlock button unlocks the driver's door only - the second press unlocks all the doors - adding the function is not that hard - its one connection and changing the programming to turn it on

after that, i want to work on the courtesy lights - i'd like them to come on when unlock is pressed - might need a relay here - the viper wire puts out a (-) 200ma signal - i will have to research what the ford wants

the defrost does not work - need to check what the ford wants - the wire puts out a (-) 200ma signal from the viper

then the arming wire - its interesting that if i press the lock with the doors closed, the antitheft is not armed - if i press unlock with the doors open, it arms - i read this here

arms on lock only with door open - it is necessary to send a signal to door trigger as well as to lock to arm factory alarm.

guess i'll be probing lots of wires with the dimm

after reading this here:

arms on lock only with door open - it is necessary to send a signal to door trigger as well as to lock to arm factory alarm.

i measured the voltage on the door trigger wire

door closed (dome light off) = 0

door open (dome light on) = 12v

press the ford lock button and i get a momentary (-) 200ma

the viper "arm" wire sends out (-) 200ma - but if i connect that wire and open the door, won't i be sending 12v through the viper unit when the dome light come on?  would i need a diode or is that built into the viper?  or does it matter if i send 12v through this wire?

Install manual text:  This wire sends a negative pulse every time the remote start shuts down or when the doors are locked with the remote.  This can be used to pulse the arm wire of the vehicle’s factory antitheft device.  Use a relay to send a (-) or (+) pulse to the arm wire.

Ok...your post said second "lock"...Its second un-lock...nice feature not necessary...You had black lead to ground ...red to door trigger...during door trigger test.?...should be positive trigger ...most fords are...
All Door TriggerBLACK/ LIGHT BLUE(+)DRIVER'S KICK PANEL

You are not going to use door trigger  wire to activate factory alarm...you will need to find factory arm wire...cant help you there only lists factory dis-arm...

Alarm DisarmDARK GREEN/ VIOLET(-)DRIVER'S KICK PANEL

Yes that is how you arm factory security...open door...lock vehicle...

Maybe somebody can give you domelight...Otherwise will have to use meter and see + or - trigger...just make sure you wire factory dis-arm and if you want to arm factory security lock doors w/ door open...then close door...

sorry for the confusion on the lock/unlock wires and the second unlock - if you select the second unlock option in the viper programming menu, the viper sends unlock down the standard unlock wire on the first press of the remote - the second press on the remote, it sends unlock down the second unlock wire - the ford schematic shows the wire for the driver door unlock:

viper STANDARD unlock wire to ford DRIVER door unlock

viper SECOND unlock wire to ford REGULAR door unlock (all doors)

it works - when i place the dimm on the wire, it reads 12v - when you press the unlock door on the ford, the voltage drops a sec - when i press the ford fob unlock, the voltage drops a sec - same thing when you press the viper unlock - i assume all 3 send that (-) 200ma on the wire and that signals the locks

---------------------------------------------------------------------------------------------------------

the disarm wire works - its a fairly straightforward connection

----------------------------------------------------------------------------------------------------------

i have looked through all the ford schematics and can't find a wire for "arm" on the vehicle - evidently, when you press the ford fob lock button, the ford signals the lock wire (and it locks the doors) AND it sends a (-) 200ma signal through the wire we use for the door trigger on the ford - this arms the ford factory antitheft

i placed the dimm on the wire on the ford for the door trigger - to see if the theory was true - that wire shows 12v when the dome lights are on - nothing when the dome lights are off - i pressed the ford fob to lock the doors (and arm the factory antitheft) and i see (-) 200ma on the wire (again, this is the wire on the ford that we use for door trigger)

the viper wire for "arm" sends out (-) 200ma when it functions - which seems ideal - no relay required (i guess) - before i connect it to the ford door trigger wire, i was asking if these wires are diode protected - or if the viper unit would care if i send 12v down that wire (when i open the door and the dome light comes on) - or if i need to add a diode myself

-----------------------------------------------------------------------------------------------

i have not worked on the dome light yet - when i identify the relay wire i will test it and see what happens on it to activate the light with the ford fob unlock

defrost - evidently it only works when the vehicle is started with the remote start - i'll test it later - not much need for it in texas

-----------------------------------------------------------------------------------------------------------------------

dome light - need a relay to send 12v to the door trigger wire - this will use the viper's timing mechanism instead of the ford's - i tested the dome output and it does have a timed output on the dome light output wire

-----------------------------------------------------------------------------------------------------------------------

arm wire - thought i could tap into the key cylinder arm wire - but there is not one - locking the door with a key does not arm the factory antitheft  (it does disarm) - pulsing the door trigger wire does not arn the factory antitheft - locking the doors with the keypad does arm the factory antitheft - but the only outputs i see coming from the antitheft module (rap module) for the keypad are connections to the lock and unlock wires

rap module schematics

http://mysite.verizon.net/respkm62/viper5301ina1995fordexplorer/id11.html

power door lock schematics

http://mysite.verizon.net/respkm62/viper5301ina1995fordexplorer/id16.html

i don't understand why locking the doors on the ford will arm the system when done with a door switch, ford keychain fob or the ford keypad

locking the doors with the viper arms the antitheft if the doors are open - it does not arm the antitheft if the doors are closed

since the viper knows when the door is opened (door trigger tire), i wonder if it does this by design -  i don't see any reason why the ford would be the cause of this

i do see the voltage change on the door trigger wire when the doors are locked (drops a fraction of a second) - guess i should check and see if it drops when i lock the doors with the viper and the doors are closed
