'97 Town Car passenger mirror replacement wiring...?

[ghs]

I am trying to replace the passenger mirror on my 1997 Town Car and have run into a problem. The original mirror has 2 wiring terminals, 1 has 6 wires and the other has 4 wires. All replacement mirrors I see online (Amazon, Ebay Parts Geek, etc.) have only a single wire terminal with 5 wires. Since the original mirror has been discontinued by Lincoln, I wonder if someone offers an adapter (wire harness) of some sort that would allow the 5 wire terminal on the replacement mirror to connect to the original wiring inside the door. What are my options?

You can find just the glass IF that is all you need to replace.
IF the whole unit is defective I would grab a Multimeter and a friend and test out the wires
your 5 wire should be ( 4- directional) and (1- heat)

I need to replace the whole unit as the mounting base is broken and the mirror adjustments don't work. I'll try to find someone who can help me with a multimeter to ID which of the 10 wires existing do I need to wire into the 5 wires on the replacement mirror terminal. Thanks!

The outside electrically operated mirror can have multiple functions depending on options.

Adjustment
Heated glass
Dimming
Then the mirror head may have other things like a compass or lighting.

This is the reasoning for other wires.

There isn't an adapter that I am aware of.

However one might be able to remove wires from the connector and use the relevant wires from the donor mirror in the connector from the old or existing mirror.

This would mean carefully removing the wires from the connector. NOT cutting and crimping. Cutting and crimping generally means an electrical problem in the future.

The passenger mirror would not have dimming function.

Connector 608 (6 pins) handles the motors and heat. Connector 615 (4 pins) is for position sensing related to the memory mirror function.

Note that memory mirrors are not directly controlled by the mirror switch but through the Driver Seat Module (DSM). I don't know if a mirror without the position feedback will work as a non-memory mirror or if the DSM would fault.

The attached wiring diagrams show the wire colors.

On ebay did you include your specific model year in the search?

Yes, I verified on the seller's page that the mirror selected would be a fit for my 1997 Town Car. Every mirror I have seen listed as a fit from any online provider (Amazon, Ebay, Parts Geek and others) have shown only a 5 pin terminal connecter on the replacement mirror.
@etinpa is correct in his post... on the original mirror, the 6 pin terminal contains the wires that control the directional and the heat functions.
I actually ended up taking apart the 6 pin terminal on the oringal mirror and the 5 pin terminal on the replacement mirror to get to the individual wires and through trial and error, was able to determine the correct wire pairings to make each function (up, down, right, left) work. The wire colors don't match up at all. I'm not sure the heat works on the mirror but I don't need that so no worries.
So, another task scratched off the list!
Thanks to all for your help!
