Relay/Voltage Regulator Question
I'm running all new wires for my car. I found a couple of parts that aren't addressed in the diagram from American Autowire and I can't find the answers in my assembly manual. There is a part that I think may be the horn relay mounted on the firewall. Going from the drivers side it is past the wiper motor. Can someone confirm if it is indeed the horn relay? There were no wires hooked up to it and no horns in my car. (Anyone have a spare set of horns?
The 2nd is labeled a voltage regulator and it is mounted up by the front driver's side headlight. The assembly manual says voltage regulator, there are many wires that go to it, but the upgrade kit from AA doesn't address this in either the engine bay or front light kits. I was wondering if it was obsolete due to the upgrade and change to electronic ignition from points. If someone can help I appreciate it!

The voltage regulator is for the alternator. The horn relay is next to the voltage regulator. Unless you have a newer alternator you need a voltage regulator, the new ones it is built in.

Horn relay is near the brake booster/wiper motor on a '72.
Also, a replacement is near impossible to find. I believe a '72 & '73 item only. Looks like this...

Hmmm, I will get a picture of what I think is the horn relay. The car didn't have AC so it shouldn't be that. Right now the alternator is an old one. I can't find the wiring diagram book I have, must have been misplaced when we moved. Does anyone have a diagram of what goes to the voltage regulator? Anyway to check it to see if it's still working? Wiring was a mess on the car.

Mine is like shadow's on my 68.
I did google ad they were saying it is on the firewall on yours. If my buddy would come over in his 72 I would look. |

Horn relays got relocated on '72 model...on to the firewall.
Trust me...1st hand experience on this.
