Seatbelt Starter Lockout..., Factory recall Options

[ConeDodger]

Does anyone know what the factory fix was for the 1975 seatbelt ignition lockout? I am speaking of the system that requires you to have your seatbelt fastened before the starter will operate. There was a recall but my car was never done.
I have called Porsche and they are going to "get back to me" after they check my VIN.

Sometimes the car will start and other times it doesn't with the seatbelt on or off.

Anyone have a picture of what their car looks like under the passenger seat after the recall fix?

The famous seatbelt interlock relay was in the 1974 model year. However, Dave Darling once posted on Pelican that there was at least one 75 owner that had the relay on their car. Maybe Fritz had too much vissen at lunch that day.

There's a bypass that can be made under the driver's seat.

Dave wrote this in 1999:

While stuck at home last week, I spent some time examining the
914 wiring diagrams in the Haynes manual. (The fever made it quite an
interesting experience--one I don't recommend.)
I managed to figure out a couple of things.
First, I traced through the wiring related to the Infamous 74
Seatbelt Interlock Relay. I studied the differences between the Euro
and US diagrams, and came to a happy conclusion. You can completely
disarm the relay, and have no effect on the rest of the car, in two
fairly simple steps. Step 1: Unplug the relay and throw it away.
Step 2: Permanently connect together the two thick yellow wires that
run to the relay's socket. If you're optimistic, you can make a small
"bridge" out of heavy-gauge wire and some male spade connectors, and
plug it into the correct parts of the socket.
But that won't keep moisture and corrosion out very well. So
if you're somewhat more realistic, you can CUT the wires off of the
socket, then either use a crimp-on splice connector and electrical tape,
or solder and heat-shrink tubing, to permanently connect them. No more
relay--you've just removed one potential "failure point" from the
starter circuit. (And we all know that it needs all the help it can
get...)

Hope this helps,

Thanks Rusty,
I figured it was simple and this sounds very simple.
It definately is an issue for at least some 75 cars. It was one of the two factory recalls for the model year. The other having something to do with fuel lines.

Rob, you are good on the fuel lines, there are no cloth covered hoses left on your car.

Your Welcome !

Martin

PS, I have seen that bypass wire, and would be super easy to make.

My '75 had the seatbelt relay junk. I cut it all out, joined the yellow starter wire, and the brown-only grounds. Nice to have it gone.

Yellow "Scotch Lock" connector, bridging the large yellow wires at the relay. You can even leave the relay in there, if you so choose. The Cap'n

Martin,
I knew I had no cloth fuel lines... I was just pointing out that there were two recalls for the '75. And thank you...

That is a nice looking 914 in the pic. Who are those two grouchy bastards staring at the motor hole?

I have not heard back from Niello Porsche. I had been hoping to be the last 914 on earth to come in for the recall but it looks like they will not be getting back to me soon.

I will deal with the relay on Saturday or Sunday I guess... Starter and ignition electronic part go in then too.

I can't believe that YOU are recommending one of those POS scotchlocks. Those things cause more grief than any other electrical "repairs" than I have ever seen.

I would not use one of those on a bycycle......
