I am facing the last couple things before taking the car to the Porsche workshop where engine/gearbox group will be reinstalled on the car, the final checks performed and the engine fired up.
One of these issues is how to put the refilling oil line back in place, it seems to be harder than expected.
Another one is about understanding what these 2 relais are for, I mean, if they are supposed to comanda the windshield wipers or are important for the engine to be fired up
Does anyone here have any idea of what these 2 relais are for?
Last but not least it would be important to get pictolures on how the cables and harnesses are supposed to be hanged in the engine bay, I mean, to replicate the way they were installed in origin.
The next week is going to be the moment when the cockpit should be seeing its lights on back again...
These positions are for the turn signal relay, (if not fitted in the centre console) Gong relay, (Chime for reminding of lights/safety belts) and the control unit "relay" for dashboard backlight dimming.
I guess this car have the turn signal relay in the centre console, so this should then be Gong and Dimming units.
By the way, it looks like you need to fit a nut on the ground point connection just behind the relay sockets.
Cheers,
Tore
Paolo, I can take pics of the engine bay on my early 95 this weekend, if it would help.

Thank you Ed,
It would definitely help, but I don't know if with engine in place there is enough visibility.
I am still wondering which are the part numbers of the 2 relais, do you have any idea? They are also far from being reachable!
in that spot my car has the gong #928.618.102.03 (replaced by the immo block in pic)
and indicator/flash relay # 1HO 953 227
my car is missing the hvac unit so let me know if you want any pics of that area behind the dash
firewall is in place behind the tank but still space to shove a camera in there.
In RoW cars, the socket closest to the driver is wired for a 4-pin buzzer (443 951 307 B) . In US/Can cars it's wired for the 7-pin gong . I believe the socket looks the same from the top so the only way to tell what you have is to count the wires going to it.

European cars should have the flash relay and the buzzer for lights on, I will have to understand which one is first and secondo one of the two sockets.
it's curious the 2 bolts that hanged in place the plastic supports seem to have a different thread step.
Here's what the bottom of those 2 sockets should look like in a RoW 993:
Thank you Jay !
1 am now trying to understand the differences between the Winingharness of my. 95 and m.y. 96, because I think the one I got used is a 96 one.
Luckily the silver 993 is a my. 96 and so I can check it and take inspiration.
1 am curious to understand which functionher the "flat" relais In the m.y. 95 ( pointed inyellow) and why the shape in the m.y. 96is so different.
This is a m.y, 95 fuse box
while this is a m,y. 96 fuse fox
Could anyone here point me out the part# of the 2 relais with the big "1" number?

It's a "bridge adapter" basically connecting two of the terminals together with a bridge (wire connection) That one connects 2 different sockets.. I agree that I think it's from 96 because I have a 95 and I don't have that one.. It's purpose is to determine the functions of the Gong for lights / belts when the door is open-
R24 is the dimmer control for the instrument lights. In 96-98's it's located in the fuse box. 95's use the same part but it's said to be located "in luggage compartment, left"
As noted above, R12 is a "bridge adapter" - just a couple jumpers in a little brick used by factory to change wiring. The wiring diagrams show the adapter but not what pins are jumpered, however, the one in your picture shows 2-9 and 0-4 jumpered. Since PET shows only one P/N, it may be they are all configured that way. If so, it appears it has something to do with lighting (fog lights, etc). PET seems to indicate it's in all MY's but my 97 doesn't have one and everything seems to work ok.

Thank you Jay,
the fuse box of the m.y. 96 in my garage doesn't have anything inserted inside the R12 socket, so since I got a used m.y. 96 wiring harness I was considering it was a good idea, in order not to have issues, replicating 100% a m.y. 96 wiring harness.
I know the car is a m.y. 95, but she will get the varioram intake layout, so I think it is a nice&very welcome unexpected surprise!
Now there is still a minor, but I suspect very important detail to be fixed before bolting the firewall/fuse box and install the fuel tank, and it is showed exactly in the following picture
The tiny black duct pointed out by the maritim blue arrow, I suspect it's the same I noticed popping out from the wiring harness in the engine bay, but what is its function and where exactly must be connected inside the fuse box?!?
Regarding bridge adapter R12....
The wiring diagrams indicate that 95's and 96's are wired the same way with regard to R12. In those MY's the 0-4 jumper allows the low beams to be on when the high beams are turned on. Without it, low beams go off when you turn the high beams on (you can still flash them, though). The 2-9 jumper sends power to the Fog light switch. 97's and 98's have those 2 jumpers built into the wiring harness so R12 isn't needed, but would do no harm if it was.
I have no idea what that black thing is. Is it just a tube or is there a wire in it? Where does the other end go in the engine compartment?
