So here is the skinny. The shop manual for the 1941 1/2 ton shows no relay for the horn. The same manual shows the 1941 car has a relay. The manual has the wiring diag. for both the car and the truck. The one for the truck is labeled car and the one for the car is labeled truck. The way I know these are reversed is that the one labeled truck shows 2 tail lamps and a license plate lamp and the one labeled car only shows 1 tail lamp.
I now need to know if the truck ever had a relay for the horn?


I didn't do it, no one saw me do it, you can't prove anything! "Bart Simpson"
