Wiring - Spare Plug ID

[addo]

As a self-confessed factory options tart, I refer both to my pre-multiplex Berlingo, and the following picture. (Click at risk of pop-ups and light grade malware...)

Based on other PSA cars I am guessing the two five pin plugs that have dual earths, are the passenger window switch and one-touch driver's switch.

The larger white plug has me puzzled though. I am of the understanding the RF remote is fitted forward of the OSR wheel under that black metal tray, beside the central locking control box. My radio is under the flip flap below the hazard and A/C switches.

Any suggestions would be helpful!

Thanks, Adam.

Hi, if you could read the small wire numbers on the wires, that would be helpful :thumbsup:

Ta.

Some more investigation confirmed the smaller blue and grey plugs are power window harness (cool! - I am parting out a late Xantia and will pillage away).

The larger white plug I am guessing is the RF locking box plug. Wire codes (as read below the two asterisks and above the single asterisk) are : M6231 (ground, obviously), 2339, 2349, 6270A, 6275A, B14, B14B, A30D.

That said, there are two brown (maroon) plugs in the location for the central locking box. One is clearly for the standard lock controller, not sure of the other - seemed an odd place for a RX/TX box! Worst case, I could buzz it all out but the rear RH side is chocked with stuff at present including a spare PRV motor on a pallet.

I've a lovely big book of wiring diagrams for my 605, and while PSA protocol for identifying items by number hasn't changed much since the early nineties, a good deal of the actual wire numbers have.

You were right, it's for the key fob lock unlock hf receiver.

Fantastic help, thanks very much.

Any ideas on the extra maroon plug near the control box (just ahead of OSR wheel arch under that black metal cover)? Haven't noted its wire numbers yet.

If it's a 13 pin brown it's for an alarm system. alut:

Could well be an alarm. It's the background plug in this photo:

I'd noticed what seemed on the slam panel, to be a location for an alarm disable switch. (Near the LH headlight.)

Are the schematics on the subscription side of Service Citroën, or do you need dealer access? I'm presuming they dropped the print books ten years ago.

On a semi-related note, is it feasible to add extra terminals into the door side multipin connectors, or are they overmoulded?

[Rustscrat]

Unfortunately on mine they are encapsulated in a resin, might be different on yours though as it's a Mk1. alut:

Ta! I suppose that helps firm up a "Plan B" to purchase used door harnesses off a later one.

Hoping to get the 'leccy mirror swap sorted this Sunday.
