Need Help with Wiring on 2.7 conversion

[kfish914]

OK I am trying to figure out the wiring for my 2.7 conversion and I see this. I talked with the PO and he hadn’t done any wiring changes, so he was not any help in why the additions to the harness. I should also point out that I am an idiot when it comes to auto wiring.
The first photo I just need some one to confirm where the wires go for me. I think from the diagram I know what they are, I just want to make sure.
Thanks for any help

I have all the wiring diaghragms for the 911 and 914's.


First, I need to know about your 2.7. Is it cis or carbs. Second,what kind
of ignition setup are you running. The way I take care of these problems
is I check the wires from the 14 pin connection. You don't need all of them,
only a few are needed to make the car run.



71 914
76 911S
66 912 V8 SBC
81 911 SC

I am running a 2.7 with CIS and stock ignition.
Any help you could give me I would be very great full. I was told I could get rid of the relay board, but not sure if that is the best way to go.
Thanks again

Thanks, I appreciate all your help. When it comes to wiring I have the worst luck at finding issues let alone this. I am not very good at reading wire diagrams.

One of my cars is a 76 911S with a 74 2.7 cis engine.


Here is the 14 pin plug from a 74 2.7 cis

1)2 yellows starter/cold start
2) green
3) green/black oil temp instr
4) green/red oil press instr
5)green/white backup
6) white or ? backup
7) blue/yellow To fuse on panel in engine bay
8) brown/white
9)green/white oil press idiot light
10) red/white thermovalve
11) blue alt control light (D+)
12) NO
13) black/yellow power sourse fresh air blower
14) red/source from alt B+


This is what will be going to the engine on the 911. Now as for the
pictures that you have you are asking for help regarding those two
extraneous wires with help pointing to them. They look maybe grey or white
coming from the number 6 pin of the 14 pin connection. They look to be for back-up lights.

Now one way to sure is if you have a contunity meter and can pinpoint if
in fact those wires end up at pin number 5 and 6 of the 14 pin connection. They
are numbered if you look carefully by popping off the cover of the 14 pin connection and you can see their color and the number pin slot they are in.
