Module under passenger's seat

In trying to get all of the electrical items working properly on my 1974 914, I found a problem with the driver's door switch, and corrected it. (That also got the irritating warning buzzer operating.)

Now, even with the key out of the ignition, I keep hearing the relay that's under the passenger seat clicking every time I open or close the door.

Is this relay always supposed to be live, and operate this way? And if so, does anyone know why?

Would appreciate any help.

This relay is the infamous Seat Belt Interlock. The same panel also holds the door buzzer. To get rid of the buzzer, unplug it. It's the smaller of the two boxes plugged into this panel.

Some 74s might have only had one REALLY big box that combined the two functions, but mine had both.

To disable the seatbelt interlock, and remove one possible failure point from your starter circuit, connect the two FAT yellow wires that go into the panel together. Solder or use a crimp connector, put shrink-wrap on it to make the connection water-tight. (Unless the floor of your 914 *never* gets wet. Sure, none of them ever do... Heh heh heh.)

Not sure why you would be hearing a click from that area, unless some part of the relay is hooked up incorrectly? It doesn't really matter, though. Disarm the starter interlock and pull the buzzer, and you can unplug both components and throw them away.

Oops... Looked over my 74 US wiring diagram (in the Haynes book) and noticed that the door switches are in fact connected to the interlock relay. I'm not sure why, but there is a connection. I don't remember my car ever "clicking" when I open or close either door, but that could just be mine.

I think that you should be OK if you remove the relay and permanently connect the two big yellow wires together.

Don't quote me on this, but I believe that on the '74 models, the door is supposed to activate the buzzer when it's open. I also believe that there are two buzzers, one for the seat belt, and one for the door, since I removed one of them, and there is another buzzing sound occurring when I sit on my seat without the seat belt attached.

So, after thinking about it a bit, I bet that the door switch is supposed to activate this 'door open' warning buzzer. I seem to remember Tom telling me something like that a long time ago, and me thinking, "Gosh that's a really dumb design."

Like I haven't ever said that about my 914 before...
