Relays
#1
Ok guys...I have a ton of relays from 71-73 underdash harnesses, and I don't know what they do. All I know is that there are white ones, black ones, 3 prong ones, and 5 prong ones. I suspect none of them are reproduced.

So...are they worth anything? How do I tell them apart?

I'm more than willing to sell them to y'all, but I can't guarantee that they will work (I have no way of testing them). If I sell one, and it doesn't work, I'll replace it until you do have a working one.

So...edumacate me on these damn relays!

Let me check your shorts!

Sounds like they might be flashers or buzzers. Got some pics?

Here’s what I could come up with:
5 prong relay is for the headlight to headlight on warning buzzer
3 prong relays for the electric seatback latches
4-prong relay for the heated back window
2 pole flashers , one for turn signals and one for emergency
It looks like the key buzzer and headight buzzer are the same one

What in the world is a headlight to headlight on warning buzzer? Is that a buzzer that buzzes when your headlights are on but the car is off?


I only had a quick look at my stuff, and found the following four relays:
#1: Unknown to me

#2: Looks like a seat belt light...correct?

#3: I think this is a circuit breaker for the A/C:

#4: Same as #2, but with different colored wires

That's what it is. Seems funny that they would have to run it through a relay just to make a buzzer buzz, but it's apparently to isolate it from the buzzer, so when you open the door with the key in the ignition the buzzer doesn't feed back through the headlight circuit.
#1 is the key buzzer, and I agree with 2 & 4. #3 might be the circuit breaker for a convertible top, or for power windows.

Are the seat belt light and headlight/key buzzer still available or in repro?
