no idea.
How do I go about instaling the OE keyless entry from say a 94 or 95 E34 to an 02/89 535?

I would check to see if you car was prewired for an alarm system first. There should be a plastic button on the right side of your trunk. There will also be a 12 or 24 pin (cant remember) connector near the battery under the rear seat. The module you have found on ebay should plug right in to the above mentioned 12/24 pin connector if your car is prewired.
I think the alarm system from a late 94/95 car is impossible, or hard and expensive enough, to put in your car. DWA is pretty well integrated into various systems of the vehicle that make retrofitting it not only cost prohibitive, but improbable.
