Mysterious Electrical

[wwest]

1988 Carrera special edition, 100k plus miles.

Two stubbed off wires inside the blower evaporator "cubby", one brown and one red w/white strip.

Relay socket, no relay, directly above the windshield washer pump, brown and yellow Heavy duty wires that then go to a connector, no connection, tucked away near the end of the car jack.

No non-working functions that I can find, oil cooler fan, condensor cooling fan, fog lights, horn, all work.

Anyone know the purpose of either or both of these..??

I think you are going to need the 1984-1989 911 workshop manual as it has the wiring diagrams.

At the moment my guess, resulting from going over the fuse load list, is that the relay/connector near the car jack is for the optional headlamp washer/washing.

in the SC there is a fan mounted to push air down and through the front a/c condenser. the fan is to the left of the washer pump. is there one of these in your carrerra? if not, I'd bet that's the wire. If yes, then it could be wiring for the optional headlight washer or for the fog lights.

Yes, that is the condensor cooling fan and it works well. I plan to take it out and clean the squirrel cage blower.

It now appears that the relay/wiring/connector is for the optional headlight washer.

Hello

yes that could be the socket for the headligt washer units on the 88 the washerpump sits underneath the washer bootle tank and the pump will make 8bar pressure also since 1985,5 the 911 had the intensive wind screen noozles as option wich sprayed cleaning solvent with 6 bar onto the windscreen (to remove bugs and heavy dirt). Check the option code sticker and download the siting 911 PET from Porsche.com to get an overview.

Now brown is the colorcode for Earth, Red/White ist the Colorcode for Power behind the ignition switch, could be the wireloom for the seperate alarmhorn could be something eles relatet to the AirCondition ( There must be one relay for that in the box )
