Thanks Bill, that is what I though but never hurt to ask, maybe someone will pipe up

Thank for the diagram Bill, that looks like it could work for me!

Thanks also Otto and Jaems - I think I have that one sorted now and off out now to connect those wires up. I really appreciate your help, I wouldn't have got this far without it!

I'm sure I'll be back with more questions soon!

Thanks

It is joined with a connector block and then feeds under the dash. Using the wiring diagram, I have traced it back and believe it connects to the wiper motor, but I can't see where it would connect. Have I got this wrong? If you could confirm if you think I am right and can tell/show me where it connects, that would be fantastic! Many thanks in advance

These go to my cigarette lighter in my 67

Thank you - that is exactly what I have! I will get it connected up now! Thanks

Do you have a link for an 83?

JJ

From 74 on they use what the can a flow chart for their wiring diagram. It is a continuous run on page after page. Once you find what you are looking for, you just follow it page after page.

The one I did for a 74 911S. I just fitted the pages together and rolled it up. in a wiring diagram like the 912, the newer cars just became more complicated to follow. So they use a flow chart.

This is one page of a 82SC flow chart.

JJ, Jaems,

Perhaps good to mention, the diagrams are accompanied by a parts. Each part is followed by one or more numbers referring to the numbers in the bottom of the diagram. For numbers (at wire ends) in the diagram the reference system is the same. The bottom line equals ground.

So, with an electrical problem with the heaterblower circuit, take a look in the list and look for the number following "Heater blower motor", which is "20". Above number "20"in the diagram you will find the symbol for heater blower motor.

As Jaems mentioned, it's reccommended to put the pages together. Unnecessary to mention is to print the diagram in color.

Thanks, I have the Bentley pages but was hoping for a nice one piece in color.

eBay got some but not the 83.

Anyhow by the time I'm done with the car, I need to do my own wiring diagram.

This is what my ECU wiring look like

You might check on the 911 and 911SC forums. They would have more information on your 83 SC. Our knowledge mainly deals with the simple early 912 cars over here.

Thanks, I like the cross training

I'm on all of them, kind of a disease...

What’s up guys looks like you guys know what’s going on recently just restored my Porsche after 12 years got it back from paint and everything together and running like a dream but my horn’s do not work when you push the steering wheel you can hear the clicking at the relay but the horns do not work does this mean my relay is gone

[Albert.belsito]

What’s up guys restored my 1968 912 and I have everything working all lights blinkers hazards. Brake lights and backup light.
But my horns will only click at the relay. No horns. Does this mean my relay is gone. ???
