14-pin connector question ('75 911S)

[cowtown]

Hi,
I'm trying to figure out where pins #7 and #8 of the 14-pin connector go, on the chassis-side of the plug on a '75 911S.

My wiring diagram for '75 lists T14, but does not have pin numbers like on the later diagrams! I've probed the fusebox for continuity with no luck.

What I'm trying to do is pick up these two wires, in the front trunk, so that I can use them in the fuel pump cutoff circuit with my 930 engine transplant. On 930 engine, T14 pin #7 is the overboost sensor and T14 pin #8 is the CIS air switch. The original '75 engine had neither of these items, so I assume the wires are just taped off somewhere.

I'd appreciate any help, or tips on how to trace these!
Thanks,
Colin

Colin, I believe this is what you're looking for:

The pinout for the engine side of the 14 pin connector is
1 yellow;starter
2 not used, disconnect
3 not used
4 gn/red; oil pressure gauge
5 gn/ye; reverse light switch
6 gn/br; reverse light switch
7 bl/gn; heater fan, not needed
8 br/bl; heater fan, control signal
9 gn/wht; oil pressure warning light
10 re; relay blower motor, not needed
11 bl; alarm, not needed
12 re; a/c compressor
13 ye/gn; relay blower motor
14 re; relay fuse panel heater blower motor

Thanks Ryan! I'm not sure where the heater fan wiring runs (since the heater blowers on my '75 are long gone). Is there supposed to be a switch under the heater levers in the center tunnel where I could pick these leads up? As far as I can tell, these levers only pull the flappers open. I don't see any switches like my '88 has. I'll keep poking around.
Thanks,
Colin
