Pin 4 : lock/unlock
Pin 5 : live +12V via fuses F25 & F8
However, where do you get the information that pin 3 is not used on Mk1's ? All three of our Xantia's are Mk1's, and they have this signal.
That would imply that the Mk1's never had a two button remote control, which is incorrect - even the manual for my mum's 1993 model shows both a one button and two button remote control as possibilities, and her's also has an alarm which does NOT arm with the main doorlock button.
So I would suggest that pin 3 is in use on cars with alarm or deadlocks
(In any case, by aquiring a two button remote control this pin can be put to use and connected to a 3rd party alarm, as all the receivers support it)

I'm trying to understand how to program new plip to IR receiver in Xantia Mk1. I can see that there are even various versions of receivers and also various version of IR plips (one button vs. two buttons), I personally saw only one button version:
I also have several (all the same) receivers (all do have 5 wires), but pin 2 (ignition) is NOT routed from the connector. Simply there's no way for the receiver electronics to 'see' this +12V.
So I wonder how such version of receiver can be reprogrammed, or how the programming will be initiated?
The receivers are all from 95'-96' Xantias, there's some sort of SPI EEPROM marked 6210 (the same EEPROM is also in the plip, can be seen on the photo). This 6210 (with 'e' sign) is SOIC8 device and has some non-standard pinout:
pin 1 Vdd (?)
pin 2 GND
pin 3 CS (chip select) or Write enable?, connected to GND in plip
pin 6 SDI (SPI data in)
pin 7 SCK (SPI clock)
pin 8 SDO (SPI data out)
all others are N/C. Anyone has idea of what is the this type and/or manufacturer of this memory?
I also looked into the various 96' schematics, there are two versions of central locking mentioned:
* standard one, all 5 pins are connected, pins 3 and 4 are both wired to 8 pin central locking module (number 6235, located in the central tunel). This smaller central locking module has NO connection to door contacts, etc. just all lock-motors, alarm and indoor light are connected.
* 'improved' locking: 6235 module has 2x10 pins, pin 3 of IR receiver is NOT connected with it. 6235 is in addition connected to direction lights and door contacts.
Any comments?

P.S. If someone would be interested, I made a replica of original plip: http://sweb.cz/Pavel.Lajsner/IRX1/
