Just curious if they are out there anywhere to be had.

Alan

Adam,
Tough to find... try douglas valley in the UK

BTW - its quite a lot of work to install...

What? An installation challenge on a 928? Unheard of !

Alan, you seriously underestimate my audacity to call you on the phone as soon as I get a set of these in my hands and grill you incessantly until you are able to walk me through the entire installation process using terms that even a small child could understand.

Just a note, I am looking for the electric version, not hydraulic.

Mark Anderson

The adjusters from Porsche are about $100 each new but I'm not sure about how to wire them up.

Jim bailey - 928 International

I believe that there are some differences in the assembly to provide clearance for the electric motor.

Alan

Mark umm - you sure about the $100 each... when I priced it out from a dealer it was >$1000 for 2 motors and a control **** - no connectors or wiring....

These are quite complicated little things - I know - I took one apart - Porsche would not charge less than $250 unless they are unloading stock...?

I could see the hydraulic motors being ~$100 - maybe?

Adam for $100 its a deal...!

Alan

What parts are involved? I have 79 that had some kind of switch with a bunch of wires to the left of the seat, was that a headlight adjuster? If it is you're welcome to it Adam, I have piles of stuff from that car tucked away here.

Jim, welcome back!

DR

Adam,
It could be simpler than you think. I have the electric adjusters, adapters and the 2 other rings in stock. They have a simple 3 pin connector which I assume is a common and a forward and reverse circuit? I had planned to do this mod myself on my 90 but forgot about it until now.

I have noticed on some 90 and later models that they are at least partially wired for this. My 90 seems to have the connector for the switch under the driver's side carpeted panel where the hatch release is. I haven't searched in the front to see if the other ends are there.

As Jim says there may be some clearance issues at the headlight area. A quick check in the Euro Pet does not show a different part number for the headlight and frame. It does however show different part numbers for the supporting arm (the upright bracket), the swivel frame (painted base), and the driving arm for 90 and later which is also when the electric adjusters are also spec'd, so there may need to be some mods there. Better yet I am sure Mark has a used set of the 90-later later parts needed waiting on the shelf just for you.

Mark is dead on, current retail is $109ish each for the adjusters and the adapters are $4ish each, the other 2 rings are cheap too if I recall.

I say go for it and let us know all the tips and tricks so maybe I will make the time to do mine!

Alan

Umm Dave no its not that simple...

Unfortunately the fenders have nothing - but its nice that the connector to near the hatch release is there - also the mounting hole is already in the carpeted panel - just has carpet over it.

There are were no issues with anything on my USA GTS - unless the GTS version had the modifed versions - USA yokes & bases shoud be fine - I expect there will be no fitment issues.

Adam that is a screaming deal - way cheaper than before. buy them while they are available - I'm thinking I might buy a spare set at that price!

DR - I have already done this upgrade it - its quite a bit of work - although I had to fabricate connectors and repair one recalcitrant motor too.

Hardest part is routing wires through the firewall. and securing them well to the movable arm. The connectors run directly from the 3 wire control in the cabin to both motors.

They actually have a complicated feedback circuit to guarantee position lock between both sides... as is often the case - the system is a bit more complicated than it really needs to be...

BTW - don't even think about doing this if you don't have H4's installed. H5 lenses don't pivot in the same way - and anyway you would not be able to aim them manually to any accuracy as you can with H4's....

As I recalled the motor is much larger than the little round cylinder (rod on USA cars) so it needs a larger cutout to clear.

Leon Speed

I ordered these with Porsche in Germany and came to about $ 300 including VAT. Problem with models before 90 is that you have to make the electric circuit yourself. I switched to the 'hydraulic' system instead - more or less same price.

Bill Ball

My collection of headlight adjuster motors just plummeted in value.

Alan

It is indeed much larger but only in that it hangs down offset underneath the yoke. It also means you cannot install it in situ as with the dummy US version and the original hydraulic versions.

Instead you have to take 20 minutes to unscrew & remove the yoke just to attach the motor (takes literally 1 second - push-twist-done) then 20 minutes reattaching the yoke...

Having actually done it - it really fits

Aryan - The hydraulic system is well known to be pretty crappy - virtually no original systems still work... I would not consider retrofitting it. Besides running that plumbing on a USA model would be more painful than doing all the wiring IMO (e.g. you have to drill for it right?). Again sorry - I think you made a bad choice compared to electric for a retrofit - but I hope it keeps working for you...

Alan

Leon Speed

Alan, I know. I just like things original. In that regard I'm pretty stubborn... I'll post as soon as it leaks..

Okay, sounds like some of you guys have dug pretty deep into this.

Any part numbers to share?

I've got an '88, so it looks like I may be into it for more than just whats contained in the headlight pods and the electrical.



So it looks like I'll need #'s 30-33 for what's inside the headlight pod.

Anyone have any part #'s for what else is inside the headlight pod? What are the "rings" that everyone is referring to? Are these what the headlights mount into? I'm assuming that these are suspended by some kind of a swivel mount?

Is there a part number for the switch and harness and are these still available?

Mike, I'll definitely take you up on your offer for your gutted '79 system. Maybe I can put some of the parts to use. Does anyone know if the switch on the hydraulic systems is the same as in the electric systems? For some reason I thought the switch in the earlier cars was a hydraulic valve, and not electrical.

Thanks all, this could be a cool project.
