1969 911T original electric panel

[siimlane]

Hi

Can anyone point me a direction where to find original electric panel that is next to the engine pictures? I've searched for two days and found exactly nothing that i could use. Im most interested in placement and attachments of the parts so the bigger resolution the better.

Siim,

Ask on the ‘911 Used Parts For Sale Forum’.
Post “WTB 1969 engine electric panel.”
Do you have 911T carbs or MFI? Other? You need to specify.

electric question : 2.0 E engine compartment

wiring 911/912 `69




From: Differences betwen 69T & 70T




911T carbs:



From: Need close pics of 2.2E engine&engine bay

Hi

Sorry, i wasn't clear enough. I have the panel but it has been modified in the past and my wish is to restore this to original condition. My car is 911T 1969 with Webers. This is my panel:



What's in the white box? I didnt see that on the other pictures and should the mount for the Hardi pump straight? Mine is a bit bent.

Siim,

The device in the white box is a ‘Radio Frequency Interference’ (RFI) suppression filter to prevent alternator noise in the radio or other electronics.
That is an original factory part.
The 3-prong connector from the alternator plugs into this device.
This device plugs into the Bosch voltage regulator (yellow arrow).





What are the numbers and wire-colors to the device (green arrow)?
You will notice connector pin numbers on the device and connector.
Associate the pin numbers with the wire colors.

Originally there was a Hardi electric fuel pump located here (violet circle).
A better solution for fuel pump is to locate a rotary pump on the front suspension cross member.
This is identical to the 1969 MFI 911E & 911S, only a different (lower pressure) pump.
(A 1970 911T was configured this way.)
Does your chassis have an unused fuel return pipe in the tunnel?
If so, you should consider a circulating fuel system (like MFI, CIS, DME and more.)
If not, you might consider a new return pipe.

Post the wire colors and associated pin numbers from the two silver relays (brown arrows) on the panel.




What are your intentions with your project? Restore to original? Make work properly? Build a ‘hot-rod’? Other?

Best,
Grady

Hi

I made some pictures about the panel.













My car didn't have extra fuel line in the tunnel. I'll try to find some pics how the fuel pump is mounted in the front.

Hi Siimlane!

I got you PM but I don't know if pictures of my set up will be helpful. Mine has been modified and I have deleted the voltage regulator in favor of an alternator that has one built in. Grady is the Porsche GOD and his advice is always spot on!

Cheers,
Kristoph

Kristoph,
Can you take more detail images?
What are the numbers on the silver rectangular Bosch box?



Siim,

OK, lets’ get this ‘straight’.

This “12” electric panel seems (to me) to be for a 1969 MFI 911E/S with (possibly) a single-stage (or no) heated rear window.
Your 911 is a 1969 911T – correct? VIN = 119121314 Engine number = 6195100.
2.0 or 2.2 liter engine

Note the images I posted above have a “10” electrical panel.

While not exactly correct for your 911T, I’m sure we can make this electrical panel work correctly for your application.

First – Do you have a Heated Rear Window?
If so, is it single stage or 2-stage (full top-to-bottom heating element)?
If you have (had) a Heated Rear Window, the gasket and body should have provision for the wires in the lower-left corner.

Please post images of the engine so we can see the configuration.

On your “12” electric panel, please confirm the wire colors and pin numbers on the two ‘silver’ aluminum relays and the MFI RPM Transducer.
There can be pin numbers both on the devices and on the connectors.

Please post a detailed image of the Rear Fuse Panel.

Please clean or ‘peal-back’ coverings so we can be sure of wire colors.

Eventually, we want to absolutely confirm that the wires go where indicated on the wiring diagrams.
You will need a ‘multi-meter’ or ‘continuity tester’ for this.
The 1969 model-year was a ‘transition’ year and many things changed during the production.

We can get your electric panel to serve properly and look exactly as if it were original (the “12” excepted – leave it intact).



Here is your (I think) Heated Rear Window Relay. It is also possible this is part of the MFI.



The numbers are relay pin numbers.
Please confirm the wire colors and pin numbers.




Here is your MFI RPM Transducer.



Please confirm the wire colors and pin numbers.



Here is the ‘other’ relay.



This may be part of the MFI.
Please confirm wire colors and pin numbers.

Overall, this may be an electric panel combined from several.

Best,
Grady

Hi Grady and Siimlane,

Here is a more detailed picture. I am guessing I have an MFI RPM Transducer which makes no sense on a 69T? Why would this be in there? Maybe there was an MFI motor in the car at one point?

[jstobo]

Models with Zeniths also had an RPM transducer that activated a solenoid on the carburetors to stop the gurgling when you let off the gas and or for emissions. I believe the RPM was 1500 instead of the MFI 1350 RPM limit. But I think a 69 should have Webers.
