Hello all,

Does anyone have the wiring diagrams/pin out of the 958 GTS headlights?

I'm doing the conversion and have a tough time getting this info. And this is one of the last pieces of my puzzle.


Thank you so much

How are the GTS headlights different from other headlights (before I start digging in the wiring diagrams.. it would be helpful to know what I'm looking for.)

I believe other than the cosmetic difference of having the black finish inside the housings, they're the same as the 958 CTT versions.

It sounds to me like he's perhaps purchased a GTS set (with PDLS, etc.) for a Cayenne not factory equipped with that option/setup?

OP, can you confirm?

Since we haven't heard back from the OP yet - I'm not wasting an hour or more digging through the 1000 pages of wiring diagrams in the service manual..

OP - if you're out there, let us know, and let us know exactly what you're trying to do..

Hello guys,

Terribly sorry for not getting back sooner.

AFAIK, the GTS headlights are similar to other 958 BiXenon headlights with the following exception:

DRL (the 4 lil led around the low beam projector).


Long story short, I am doing a face-lift conversion on my 955 (S with Air suspension).

I need to repin the 955 headlights wiring harness to work with the 958 GTS headlight sets (I've seen it been done before but couldn't get in contact with the shops who've done it).

With that note, I'd need the 955 bi-xenon (w/ air suspension) wiring as well if you don't mind (I understand that this is the sub 958 forum)

Thanks,
Kev

More info:

The 955 headlight (bi-xenon) equipment with Air suspension comes with the following harness.





The black end goes to the wiring coming from the car.
The white end goes to the headlight's connector.


The 958 headlights does not have this adapter cable as the headlight's connector is the same plug (as the black end's on the adapter you see here) that connect directly to the car's wiring.

However, the pins are different and I'd like to check and corresponding with the diagram to make sure that everything is as how I measured via the multi-meter.

That's the first part of the puzzle. Once the re-pin is done, I'd then need to make sure that the internals of the GTS headlight accept the signal (if everything line up) and the headlight CAN-BUS modules internally is working or if needed, to be bypass.

Ideally, this would be the best scenario, a lot of work, but done properly.


However, if this doesn't work, then I'd need to transplant the internals of the 955 Headlights over to the 958 housing AND redo the headlight's wiring myself.

Hopefully the first scenario would work out, then I can definitely share the results and the solutions with everyone.

Here are some pics of the progress so far. I know that this may not suite everyone's taste but it's a project that I'm working on:

Thank you so much.

Can you please help me with the 955 S (Air Suspension) diagram as well?

Thanks,
Kev

Probably if I find I have 2-3 hours to wade through the 11,000 pages of the 955 service manual. It will be a while.

Thanks a bunch again.

I'm terribly sorry if I didn't get the chance to make it clear earlier. I meant the Headlight Harness wiring diagram for m 955 CS with Air suspension ( know the they're different for the ones without Air suspension due to self leveling).

If you do not mind, is there a way that I can have access to the manual so I can check it out instead?

Many thanks.

You can probably find a manual on ebay. Or sign up for AllData's DIY on-line program.
