Can someone tell me or send a pic of the horn relay location? Thanks
Also trying to hook up my rear speakers but can’t tell or read the wiring diagram for the correct hook up. I see a blue wire coming out of the front radio switch but don’t know what it’s used for. I have the front speaker hooked up but need to connect the rears and the switch on the radio for balance.
Thanks again

Horn relay is to the upper left of the brake booster, might have a plastic cover on it.

Not sure what the blue wire is, but suspect it may be a power antenna wire.

Sure someone will chime in, but do you have a service manual? That will help drastically.

pretty sure its under the instrument cluster drivers side. by the wiper switch iirc

Thank you for the information. Yes I have one but it’s a copy of a copy and can’t really see the diagrams.

I believe a blue wire is for a single rear speaker.

Pretty sure the relay behind the dash is a blinker relay, the hazard flasher is in the fuse block.

Here's a pic of the horn relay 69-72....

That relay (above) is for 70-71' cars. It was moved under the dash for 72'. On the driver side.

The wiring is different.

Very interesting, I had no idea. Thanks for the clarification, note made!

Thank you I found it now. Went nuts looking in the engine compartment.

Lol, same here when I got my first 72' car. I was used to seeing it somewhere on the firewall.
