While installing a stereo I found this loose 4 pin connector whose wires come from the the area behind the HVAC controls. Though it might be an old radio connector so checked it for switched or unswitched 12v with my meter. Pin 3 does seem to be switched 12v but when I put my meter to read voltage between ground and pin 4 the blower motor for the vents comes on very weak as if it's drawing current though my meter. Weird! Just wondering if something has became disconnected that should be but all of my controls for the blower and everything else seem to work fine.

Does this connector look familiar to anyone? Sorry for the bad focus on 1st pic.

Did the car have A/C?

Posted by: willamp Nov 27 2010, 03:26 PM

Yes, I thought of that too. I don't know if the car had a/c at one time, it's been restored some time ago. I looked at the used a/c system I have from a different car and this connector wasn't used there. But that may not mean my car didn't have a/c with a different setup. I'm betting you're right, This must have been plugged into a dealer a/c. Anyway, the switched 12v is hooked up to my stereo now and seems to be working fine.

After posting it occured to me that the spare tire well seems to be intact so didn't have a condenser up there unless the bottom of the well was replaced. It still has the tow loop but I'll take a closer look sometime to see if I can see any signs of replacement. I don't see any holes for the a/c hoses either though.

'fasten seatbelt light'

Posted by: 914Sixer Nov 28 2010, 07:37 AM

Jeff is correct, seat belt light.

No, Sorry, it's not the seat belt waring light. I pulled the ashtray and felt the back of it. It has two spade terminals coming out the back about 1.5 inch apart. Currently nothing on them. The mystery connector is 4 pin about 1 inch wide.

I just put the connector back into the console where I found it. Doesn't appear to be anything important.

Trace a few of the wires and see if they have stock connector ends or cheapie colored plastic crimp on connectors.

Looks like my aftermarket stereo power harness plug. I have a Kenwood. Maybe?

If it has a Yellow,Black,Brown/White and Gray/Red it is the Fasten seat belt light and plugs into the light.

On my 75-76 there are 2 spade connectors, as mentioned above, goin to the fasten belts light. And they're red (power) and yellow/red which I believe was a negative switched wire going to the connection under the passenger seat.

On a '73, it's 4 wires for the seatbelt warning light.

- Yellow
- Brown/White
- Black
- Gray/Brown(?)

From the pictures posted, it certainly looks like the fasten seatbelt light connector.

Maybe I have a later fasten seatbelt light with the 2 spade connectors. So my car is a 73 and has the older 4 pin connector.

Which would explain why it wasn't connected ...
