My 1995 6-cylinder XJS coupe came with a remote, which the previous owner had purchased but never programmed. I searched through the forum to find programming instructions. My car does not have a valet switch. I followed these instructions, from dsetter, which worked. Look at post 6:
https://www.jaguarforums.com/forum/x...994-xjs-89554/

I attached some pictures.

1. Open the center console
2. Unscrew the five (5) Phillips-head screws holding the center console in place
3. (See the first attached picture) This is the remote that came with the car and the paper clips I used to replace the valet switch
4. Remove the center console
5. (See the second attached picture) This is the connector you're looking for. It has one yellow and white wire, which you'll need to short (connect) to the black wire (ground)
6. (See the third attached picture) This is how I did it. I unbent the paperclips and shoved them into the connector, into the two slots corresponding to the yellow and white wire and the black wire. Pressing these clips together shorts them. Separating them unshorts them.
7. Next, I followed the instructions from the link above. It took some fiddling and a few dozen attempts, but it finally worked.
8. Ignition off, key in
9. Yellow/white wire not shorted to black
10. Do the next steps in a few seconds
11. Ignition on, key in
12. Yellow/white wire shorted to black
13. Ignition off, key in
14. Yellow/white wire unshorted, then shorted, then unshorted, then shorted, then unshorted, then shorted, then unshorted, then shorted, then unshorted
15. At this point, the car chirped
16. Press the button on each remote you want to program, in turn, up to five. If you have fewer than five remotes, press one of the remotes multiple times, until you get to five total remote presses.
17. Car chirped with every remote press

Done!

 

Easy enough. Here is a video I made of it using a toggle switch :


I like the toggle switch because its cheap to have it there and I can program other remotes, an also turn of all the alarm function of and just have plain keyless entry.

 

Programming remote. Under my console , 94 xjs , I find 4 wire plug not two , Any ideas ??

 

If you can take a pic of what's in there, it may help us sort it out for you!

 

On my car, also a 94, the plug is a 4 wire plug but there are only two wires connected, a black and a yellow. on pins 1 and 3. Those are for the security/valet switch.

Cheers,

My 4 wire plug. Under cubby has 4 wires blue ,blue w red green green w stripe not exactly sure on colors but no black and no yellow. With ignition does the yellow have voltage? With ignition off does yellow have voltage? I maybe able to source it and can find ground or make one . I have looked in my service manual ...the big green one. But haven't found it on one of the wiring diagrams ....still looking

 

My recall of the voltage is that there is some digital 0-5 v signal with the ignition off.

 

Ok guys . I took my camera to take pic of 4 wire plug and while there thot I'd look one more time for yellow and black. Unscrewed wood console that hold window switches etc, lifted it gently and peered in using glasses and shop lite. No luck put it back. Observing carpet or more importantly that the wires came thru the carpet I took a utility knife and cut carpet as far as possible and pulled it apart... Aha a small black taped wire! Gave it a tug and low and behold the elusive yellow and black valet plug. From there it was follow instructions . I used two small wires bent and jammed into plug in lieu of paper clip and or toggle . Gotta say I jumped when the chirp and horn beeped . I programmed a generic module ($25) and it works great !!! Oh yea it worked first try. Thanks for all the help and someone tell me what the 4 blue wire plug is.

 

I believe the other plug is for the mobile phone, power and radio mute?

 

Hmmm, I don't think a factory phone option was available of the MY94 cars? If I remember correctly it was introduced in MY95, but my memory could be foggy

Cheers,

Allan
