This is a pictorial for the 2010 – 2012 Lincoln MKZ.  The sister vehicles, Ford Fusion

and Mercury Milan, should be the same.

The pictures are from a 2012 Lincoln MKZ.  This car has a standard key ignition and

the factory alarm.  Install was for Remote Start with Keyless Entry.

Disassembly:

Remove the drivers side lower dash panel by pulling in straight away from the dash.
It has four snap fasteners, one at each corner.

Remove the knee plate by removing the four 10MM bolts indicated.

Remove the lower steering column cover by removing two Phillips (screws shown by the

Yellow arrows) and one Torx T-20 machine screw ( Red arrow ).  Separate from the upper cover and remove.

Pop out the trunk release switch panel by reaching behind the panel and pressing on the four retaining tabs

( two on top & two on bottom ).    Remove the passengers kick panel cover by pulling it straight rearward
and then up from the door sill. 

Here is a picture of the left side of the steering column and the ignition connector.

Important tid-bits…

This car had a “HA” stamped key.  Ford is in the process of switching to 80 bit encryption.  Any key

 with “SA” or “HA” is capable of 80 Bit Encryption.  The easy test to verify 40 or 80 bit is as follows:
Connect a DMM to the PATS power wire ( Light Blue/Black ).
Switch OFF without key = 0V
Insert a working key in to the ignition switch.
Switch OFF with key inserted = 0V     40 Bit Encryption
Switch OFF with key inserted = 12V   80 Bit Encryption
If you have 80 Bit, you will need a bypass module capable of 80 Bit systems.  Currently DEI PKTX,
Fortin EVO-Ride or the iDatalink KLON process.
If you have 40 Bit, any bypass module capable of PATS3 should work.   I used a DEI
1100F bypass module ( ADS TB with ADS TB FM firmware ) but there is one important
wiring change.  The bypass modules W2W ground input must come from the PATS
Ground wire ( BLACK/ Violet ).

Factory Alarm

To disarm the Factory Alarm, the remote start must pulse the Ignition wire,  the bypass module ( GWR in W2W mode )

and, according to some, the Accessory wire.  Some remote starters have a programming option to do this.  The Ultra Start
U1272 I used has an option to pulse GWR and Accessory with a disarm.  I wired a relay using the disarm output to pulse
the vehicles Ignition wire to achieve a Factory Alarm disarm.

One Touch Start

This car has one touch start with built in anti-grind.  If the R/S system is capable, a fixed crank time will work fine.

Soldering is fun!

Very good write up on these cars. Havent done the MKZ, but I have done the fusion and milan. They are pretty much identical.
To master and control electricity is perfection. *evil laugh*

If you pulse the ignition/accessory, granite it disarms the alarm but turns the radio on as well. If you bump unlock by accident in your pocket this could be a problem.
I drink current, eat ohms, and bleed voltage

Personally I think you are doing a grand job and Racer James, know one has a go, to critique something after the event is only human nature especially if they thought of it first 2012 Lincoln MKZ Remote Start Pictorial -- posted image.

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.

i believe you only need to pulse ignition and disarm only of you do an alarm/ keyless with non factory remotes. a one button will disarm when you remote start with transponder and ignition.

Are you pulsing the ignition to wake up the GEM module?

No, the Ignition pulse was only for the Factory Alarm disarm. This car did not exhibit the typical Ford GEM issue with the door Unlock going to sleep and needing a wake-up trigger. Think the newer Fords with the Smart Junction Box ( SJB ) don't have that problem.
Maybe an installer with a Ford dealer account can chime in with more info.

I've done hundreds of newer ford's with the SJB and have never had to wake it up for lock/unlock
