Keyless Entry where is that damed plug!?

[bondheli]

I have a 1990 525. I have heard that there is no plug, that the plug is located in the driver's kick panel, that it is a black 12 pin plug located under the rear seat (passanger side) next to where battery should be (mine is under the hood), that it is a green plug located under the rear seat (driver's side), and that it is a black 12 pin located under the rear seat (driver's side).

None of these seem to be true for me...
In the driver's kick panel there are 2 yellow circular plugs.
Under the rear seat passanger side there are two 2 pin black plugs unaccounted for.
Under the rear seat driver's side there is a 26 pin green connector, and a 5 pin green connector.

Help! I have read almost every post on the subject as well as the bmwe34 write up, and still no luck....

In up to 1990 USA drawings, there is no reference to any Antitheft (Keyless) device, but in the wiring diagrams, there is a "Not Used" X252 connector in place of the Antitheft module connector for later models. It is a green 26 pins below LH rear seat.

I've prepared you a collage of the drawings with all info related to identification and location of X252.

Have no idea on what you can connect there.

Thanks for your reply. Does it appear to you that this 26 pin connector was used for the 88 - 91 keyless entry system? Its hard to tell from the picture, Is there more actions than just the 4 door relays? I bought a "plug n play" keyless entry system from bmwalarm.com, and if I can't get this working in a day or so, I'm going to have to return it.
thanks

here is a link (http://bmwe32.student.utwente.nl/) that might be useful it for e32's but they are very similar.My dec 89 manufactured 535 has the receiver next to the sunroof switch(I always wondered what that was!)and the led in the dash vent grilleClick on retrofits then keyless entry :)

That plug on the earilier cars in no way matches the 92 up factory keyless system. Does anyone have a pinout for the x252 connector ?

The guy said it was a black connector next to the battery. He was less knolageable than I was. When he sent me a picture, it was of the amp connector....

hmm I don't have that receiver. A label in the trunk says I am wired for a phone, but I can find nothing about being wired for an alarm. I have read on other boards that the keyless entry is located in the drivers kick panel on an e32. I have takin that off as well as the underdash and searched for about an hour for that connector or any wires with yellow dots that match the color code. Nothing.

drawings, also had to complete using e32 1990 drawings.

1990 model is wired to use the infrared system (like it, my car uses one). This device is to be located under the LH rear seat in the 26 pin connector, also uses the 5 pin green connector X331, and works in combination with X335 4 pin green connector plugged into K91 relay (OBC antitheft horn relay also below LH rear seat).

The system also includes an infrared detector located in the center front side roof (around the area of the sunroof control, and also uses the infrared and red led's located over the dash, about the center of the A/C grill.

Attached you will find an excel sheet with the pin assignments I have been able to trace. Please let me know if you find something else not shown in the sheet. Also red lines are from e32 and not confirmed at all in e34 drawings. Let me know also if wire colors change in any way, or additional wires, not shown, are found in the plug.

I had an aftermarket keyless entry put into my car, 1990 535i and the wiring was apparently in the driver's kick panel. The whole thing cost me about $100 installed with 2 remotes. Works great. Apparently other things can also be hooked up, flashing light with locking, horn, etc. I just wanted lock and unlock and am happy.

Did you ever get this connected? I bought the same system for my 1989 525i
