Extra wires in the head-light loom

Post by Robsey »

Hi all,

I am a firm believer of no question is a stupid question, but here 'should' be a simple question.

If you have read my other posts, you will know that I am upgrading the original wiring in my 1983 van to later spec CE1 fusebox wiring.

I have all the looms, so it is 'mostly' plug and play.
I have made a few repairs where wires or connectors have looked the least bit dodgy.

I have only one question... my front head lamp and horn loom.
I think the loom is from a 1987 DJ van.
But I have got these two wires that dont appear to go anywhere.

These are:-
A single connector with a white wire near to the yellow fuse box loom connector.
(Main beam left?)
And a single yellow wire with black stripe, in the same location.
(Dipped beam right?l

Image

Being single pin connectors, I presume that they go to a fused link or another fuse box connector.
But there is no mention of any connectors here in Bentley or in Haynes.. at least not that I have noticed.

The wires appear to be part of the original loom, as they are within the plastic sleeving and taped up within the factory loom.

The wires emerge at a two-pin connector approx. 8" (20cm) from the right head lamp connector.

Any thoughts or suggestions.???

Ignore the spiral bound black fabric Tesa tape.
That is just my OCD wanting to 'tidy up' the loom spaghetti.

Referring to the Bentley could it be for front fogs? White with a yellow trace (but may differ as Bentley is American)
But there should be 2 x 2 pin connectors T2a and T2b referenced in manual.?

I considered that, but pin C22 is not populated.

It is clearly not retro-fitted wiring, so it cannot be an upgrade relay loom.

Head scratching continues.

Looks like it could be a square headlight loom

I thought about that too, but I was a bit confused due to wire colours.

There is no dipped-beam feed on the inner light units.

I would have expected white and a white / black for high beams.

I believe those are for the dim dip circuit. I guess the loom you have came from a UK van, and in which case it would have had a resistor next to the offside headlamp. The white-ish two pin connector you have at the headlamp end connects to the resistor. For the two yellow single pin yellow connectors, I believe the white one goes to some terminal on the fusebox and the yellow/black joins the loom going to ignition and dash switches. Have a look at the UK wiring diagram: http://syncrosport.com/info/wiring/VW_T ... ghting.pdf
The resistor is N98.

By crikey,
I think you have hit the nail on the head.
:ok

Thank you very much for that.
I hate not knowing stuff.
You sir, are a legend.

Yes dim dip , which must be disconnected before you can successfully do the relay upgrade

I am part way through removing the plastic tubing.

I will go through the loom and connectors, and rewire a pair of relays to be triggered by the dip / high beam switch output wires.

So that the wiring is built in as it should have been in the first place, rather than an after market remedial upgrade .

-
UPDATE: -
Wiring checked, the extra wires removed from the loom, and the loom tubing has been tidied and sealed up from the elements.

It looks like I need to put my relays close to the fuse box - interrupting pins A21 (white) and B22 (yellow).
