77 FJ40 - needs a Horn, connection help

[CardinalFJ60]

Well....as I dig into the my 'new' 40, i realized the horn no workie. I guess there needs to be a horn (or two) for it work. hmmm....

I don't know where the horn elect. leads should come from. I have connectors that are dangling from each of the headlight harness right near the plug that goes into the lamp itself. - I think they are green or blue wires. Is this where the horns should plug into?

thanks!

Here's what you need:

OLD FASHIONED OOOGA HORN

I've got electrical diagrams for a '74 & '75 FJ40 but I'm not sure that would be much help

Had one for the '76 but I'm pretty sure that went with the '76 to CA

I realized my chassis manual is for a 79

...I've been pouring over the manual that came with the 40...a Toyota Chassis manual. In looking at the wire diagrams....it's for a 79. (D'OH) Anyone know how close the wiring is between the years??

Could I just rig up my test light and peer through the hood when I hit the horn?

Oooga!

Hey!! I think you're on to something!!!

Before you start chasing wiring gremlins, I would take the steering wheel apart and clean off the contacts in the buttons and the column. They tend to get corroded.
