Can someone tell me if a 68 Ford F600 has a horn relay,and if so,where is it.Can"t get power to horn.Everything in steering wheel seems intact.Thx

 

If it has the same horn mounted to the inner side of the radiator support, it should have the relay on the passenger side inner fender.

Good grounds do wonders for electrical issues.

 

Have you tested the horn with 12v going directly to it? If you can, follow the smaller wire from the battery side of the starting relay and the next thing you run into is the horn relay.

 

Actually I thought it would have the same horn relay as a pickup also. But it doesn't. In my 65/72 truck slide it says:
67....F-T500/1000......not used on units built from ser #B12,001.
It prolly has a stud type of relay somewhere. There are some of these listed for your F600 but Ford does not say what circuit they are for.
