Adding Lane assist to a 502A

did some more digging.
Pulled the cover off my rear mirror mount and got a closer look.
Yep, ribbon cable from the sensor that goes into the mount and probably to a processing board inside the mirror housing as I've found some (vague) references to.
So, unless I can transfer over the workings from the Taurus/Lincoln mirror to the f150 housing, this might be dead in the water without buying a 1400 dollar f150 AHBC/LA mirror....

Interesting read I ran across on a ford fusion site:
Lane Departure Warning - Overview
The Lane Keeping System (LKS) has 2 functions, lane keeping aid and lane keeping alert. The Lane Keeping System (LKS) utilizes the camera located in the IPMA to detect and track the road lane markings. The lane keeping alert detects unintentional drifting toward the outside of the lane and alerts the driver through steering wheel vibrations and a visual alert in the IPC message center. The lane keeping aid assists the driver by automatically providing steering torque to help the driver keep the vehicle in the lane.
IPMA (Image Processing Module A)
The IPMA is integral to the interior rear view mirror. The IPMA contains a forward-looking camera that is used to detect the position of the vehicle within the lane.
Camera Windshield Defrost Heater
The camera windshield defrost heater keeps the windshield in front of the IPMA clear of frost and ice. The IPMA uses input from the front camera and the ambient air temperature to turn the camera windshield defrost heater on and off. Voltage and ground is supplied to the heater by the IPMA. The heater may be commanded on if the ambient temperature is below 5°C (41°F).
Camera Windshield Defrost Heater
The camera windshield defrost heater is a resistive-type heater grid that is adhered to the inside of the windshield directly in front of the IPMA camera.

Automatic High Beams
The automatic high beam system uses an interior rear view mirror mounted camera (IPMA) to monitor surrounding traffic conditions and high beam usage. The automatic high beam feature is active only when the headlamp switch is in the AUTOLAMPS position.
The automatic high beams can be enabled/disabled in the IPC message center.
During nighttime driving, if it is dark enough and no other traffic is present, the IPMA sends a message to BCM, through the GWM to turn the high beams on. When the system detects an approaching vehicle's headlamps or a preceding vehicle's rear lamps, the system turns off the high beams. When the approaching vehicle's headlamps or the preceding vehicle's rear lamps are no longer detected, the high beams automatically turn back on.
Auto high beam request > IPMA Indicates to the SCCM (Steering Column Control Module) a request for the high beams based on the IPMA camera input.
===
Rain Sensitive Wipers (if equipped)
When equipped, the rain sensitive wiper feature replaces the intermittent wiper feature. The rain sensitive feature is active when the wiper/washer switch is in any of the 6 auto/intermittent sensitivity settings. The setting closest to OFF is the least sensitive to moisture, the highest setting being the most sensitive to moisture.
The rain sensor sends data through the LIN to the driver side windshield wiper motor. Based on the data received from the rain sensor and the auto/intermittent setting from the wiper/washer switch, the system automatically activates and adjusts the wiper speed and frequency when moisture is detected on the windshield.
Rain Sensor
The rain sensor uses an infrared beam to optically sense water on the windshield. The intensity of the reflected beam is measured and compared to the intensity of the transmitted beam. If there is water on the surface of the windshield, the beam distorts, reducing the intensity of the beam. If the beam is not reflected completely, it is interpreted as rain on the windshield and the windshield wipers are activated.
A gel-type lens is used as the interface between the rain sensor and the windshield. If the lens is missing or damaged, the rain sensing wipers can be inoperative. The rain sensor gel-type lens can be replaced separately on a rain sensor of this type.

So, it's confirmed.
The lane departure camera, image processor and firmware/software is made by "Mobileye". They're a tier 2 supplier for lots of manufacturers.
The camera is (obviously) in the front of the mount, but there's a processor hiding in the mirror housing itself that the camera ribbon cable runs to. That processor interprets the camera's lane imaging information (and AHBC) and tells the truck what to do accordingly.
So it's a complete mirror swap to one with the appropriate hardware or; swap the Taurus guts into the housing of the F150 mirror and hope it's talking the same language as the F-150 architecture......
The part numbers are very similar:
F-150 - FU5Z17700R
Taurus - EU5Z17700H
First letter is the year designator (E=2015, f=2016), U5Z I can't quite ferret out but it looks like an outside supplier reference of some sort (probably Gentex), 17700 is for a mirror part group, but the last letter is probably the difference between one model and the other. That one letter on the modern ford numbering system can be the difference between a minor revision, a different angle on the mount itself or maybe not being able to talk to the platform and not crossing over at all.
Might take a break for a week or so. I'm pretty tired of digging and reading about the system right now....

Normally a supplier code is not part of the part number. You're correct that gentex is probably the supplier. Brand motion makes get be able to sell you the correct parts as they often work with oems and tier 1s for aftermarket. You are on the right track with the last letter being a minor difference. That said, I wouldn't use it without knowing the difference.
