And just to really wiz me off, the same car as the UK Mondeo with different wiring colours, I recognise the connectors.

Info update:

Excellent point concerning the remote starters disarm signal ( as wired - a pulse to ACC, IGN and transponder bypass )

causing the cars radio to come on ( if it was left on when the vehicle was last driven and exited ).  An errant unlock
could indeed cause problems.   Had the customer do a couple of tests to make sure the auto shutdown happened and
the actual time period involved.  At exactly the 10 minute mark the radio is turned off.  The doors do not automatically
re-lock.

Sorry to revive an old thread...but ill be doing a 11 mkz w2w with an idatalink ads al ca and ads-al(tb)-fm2 software. So for factory disarm you simply wired a relay to do a NEG, or POS pulse to ign, accy, and gwr from the bypass? I'm a bit confused being gwr is usually a negative and I don't want to zap a bypass dead

The pulse to the vehicles Ignition and Accessory circuits must be the required (+) polarity and capable of that circuits

current needs.  If you use the R/S's Disarm or GRW outputs to do this, they must be wired to control relays to make the
polarity conversion and supply the current required. 

You didn't mention which Remote Start system you planned to use.  Some of the newer Remote Start units have a

programming option that will do most of this for you.  A few examples below. 

Compustar CS800-s

   Opt 1 Opt 2
1-06    Ign + Acc Pulse With Disarm OFF ON
1-06 Ignition + Accessory Pulse with Disarm – This option will pulse the ignition and accessory wires on CN1 at the
same time the disarm wire pulses. Most new Ford vehicles need the ignition and accessory pulsed to disarm the
factory alarm.

Audiovox Prestige APS687E  Bank 3 options

Opt 1 Opt 2       Opt 3
23rd    Ign & Accy Relays     No Pulse w/Unlock       Pulse Ign, Accy, &   Pulse Ign, Accy, & GWR w/Unlock 
     GWR w/Unlock     Follow 1 S w/ASD Pulse

Basically, to disarm the Factory Alarm system, you must pulse the Ignition and Transponder ( via GWR control input.)

As mentioned, some also believe the Accessory wire must be pulsed.  ( Pulsing the Accessory wire won't hurt things
if it is not needed.)  Perhaps the best description of the process is using DEI Tech Tip 1098, as it has a diagram of the
additional circuits necessary  :  https://www.the12volt.com/installbay/file.asp?ID=1123

Soldering is fun!

Thanks for the reply, ill be using a viper 4105. The diagram you posted...requires the common terminal to the + keysense wire...i cannot find a listed +keysense wire for the car?
Now I got the need to pulse + ign and accy, but confused on the pulse the transponder and/or +keysense wire...

Here is an updated photo of the car main ignition connector with the Keysense wire marked.  You can ( and should )

test this wire with your DMM prior to making the required connection.  It should go to +12V when a key is inserted
into the ignition switch.

Your Viper 4105 has a GREEN/ BLACK (-) 200mA FACTORY ALARM DISARM OUTPUT that is used in TechTip 1098.

Going W2W will make things easy when following TechTip 1098.  The Viper Disarm wire is used to pulse the two
relays and supply the Ignition and Keysense signals, while the Vipers Unlock output will pulse the bypass modules'
GWR input wire.

Soldering is fun!
