1970 911 T Wiring Diagram

[Three56SC]

I have been producing wiring diagrams for 1950 to 1973 Porsches for about 10 years, but I don't have one for the 70 or 71 911T - I do have one for the E and S with MFI but not for the carbureted T.
I need some help and have a few questions for those more familiar with the model that I am. As far as I know, there is not a specific factory diagram for the T, at least I've never seen one, but if there is, that would answer all my questions. I know there is a diagram for the E/S models.

1. I have removed the MFI components from this section of diagram but left the wires in place - I assume, like other Porsches, that there is only one wiring harness for all models, and unused wires are in the loom - maybe taped back, maybe not. True?
2. I presume the carbureted T has an electric fuel pump (different from the MFI car) - is it wired the same as the MFI car?
3. The Yellow #50 starter wire on the MFI model has a leg that goes to the MFI relay and the Thermo Time Switch - is the starter #50 circuit the same on the T?
4. The Throttle Micro Switch on the MFI car goes to ground through the MFI stop solenoid - does it go straight to ground on the T?
5. Is the '71 car (more or less) the same as the '70MY?

Thanks for any info you can provide.

Hello - did you ever find a wiring diagram for a 1970 911T? Anecdotally I heard that the 1969 911T wiring diagrams were the same for 1970. I am looking for a diagram for a 1970 911T.

Hi Greg, it was nice to speak to you at the LA Lit & Toyshow. The 1970 drawing is different in many ways compared to the later years. Please note that the factory drawings also has several faults compared to the original wiring and how it originally was installed in the car. The 1970 car's have the fuelpump in the front, the fuseboxes are differently wired and other wire colors were used. Just contact me at info@kroonwireharnesses.com and we will help you out / review your drawing.

I am restoring a 1971T coupe. I have one of these for most of my cars. They are well laminated. They are on EBay. Cheers
