how do I stop my headlights popping up when I switch on my sidelights?

Hi Hilton
Tried moving the wires in my plug this evening and it didn't quite work for me as planned - typical? With the wires in position 1 & 3 in the Country connector plug my lights still come up and they now light up in position 1?
I also noticed that I don't have the Dip-beam unit - someone must have removed it previously.
So not sure why my88 is acting so strange on this? Any idea's?
MAny Thanks
Steve

Thats great Hilton
Thanks for the description and photo's. I cannot seem to find my "dim-dip" module so guess the last owner may have removed it. Might be why my Headlights don't come on in dip mode.
Like the thought of having my headlights come on in dip mode whilst they are down.....have you got a photo of how this looks on your 89?
Enjoy the weekend and thanks again.

My 89 is up on stands at the moment, so I'm loathe to climb inside it to have a look up under the dash or behind the glovebox until its securely on 4-wheels.
A local who has an ex-UK '88 SE posted on the 928uk e-mail list last night saying he'd changed his coding plug and had it now behaving "normally" by world standards including headlight washers.
Here's the guts of that thread:
Starting with location in an '88:

There is another 3pin socket a bit further aft than the one you're looking for that in my 88SE has nothing plugged into it. You can tell them apart as follows. The dim dip coding plug (the part plugged into the socket that is part of the wiring harness) has male pins in the plug, and obviously female pins in the wiring harness socket. The other "red herring" socket that is a bit aft has male pins in the wiring harness part.

The coding plug is a 3 pin plug with only twon pins in it and a wire that bridges pins 2 and 3 to enable dim dip (It bridges pins 1 and 2 for non dim dip operation but those of you with non late 87 or 88 cars won't be interested in this anyway) It has p/n 928.607.422.00 and is labelled "Adapter fur codierung"
Removing both control unit and coding adapter results in the lights working normally (like all other 928s) but as Paul mentioned the headlight washers stop working.
Having never seen the WD info about the coding plug before - I must have been asleep - I'm about to change my coding plug to non dim dip mode and plug it back in to see what happens ...... or not.

"Only M061" on a wire joining the White/Blue wire to the Green/White wire.
"Not Applicable With M061" on a wire joining the White/Blue wire to the
White/Black wire.
Removing the link will leave the wiring incomplete, the link needs to be
swapped over so it connects C11 and C14.

See the bit quoted in my post above by Smiffy for colours of the wires, as I couldn't see numbers on the pins in my '87.

Hi Hilton
Yes caught that listing on 928.org.uk and Smiffy's wrote up. Will have another check & play with the connector next weekend now and see if I can make any more progress.
Many Thanks

If you can't read the numbers on the plug (I struggled but I knew I started with 2 and 3 bridged so finding 1 was EASY) get back to me or PM me and I'll go look and take a photo - you can relate it to the angles on one side of the plug.

As noted above and in my original note its 1 & 2 (ROW) or 2 & 3 (UK) linked not ever 1 & 3
As to the pin identification hope this helps:
Pin 1 car side wiring is White/Black wire
Pin 2 car side wiring is White/Blue wire
Pin 3 car side wiring is Green/White

Those look like 7" H4's - they look a lot different (lens pattern) to the 8" style.
Do you know if he added this or PO added it or does it look stock? What year is this one?

Thanks for all the help from everyone. I eventually managed to sort this with pins 2&3 jumpered in the country code plug by the LH ECU as has been noted here above. First time I tried this the pins moved out of their new position when I plugged it back together so it didn't work. Got the pins to stay put and click into the small holder clip this time and now my lights work like the other model years - stay down in Position I and up in Position II.
I can concentrate on my LED side light upgrade no this weekend.
Thanks everyone again for your help.

I can't believe it's taken me so long to try this again
The first time I did so I was irritated that I lost the headlamp washer function
However I decided to try again because I'm going to be on track tomorrow and there is a requirement to have lights on
I should be able to get away with front fog lights, and if so then I should end up with photos that will contrast with this
