horn wiring

[wuga]

On my 1931 Model A, I have a Model FM horn that has two wires going through an access hole to be attached inside. I thought I had marked every wire location but I cannot figure out how to attach these wires to the armature. Please, help.
Thank you

Here's a picture of the wires.

I may be wrong but I don't think it makes a difference with a DC system.

Thanks Bob, it works.

The horn has a series wound field so it has more torque and can be connected without concern for polarity. The male bullet pins fit into the groove of the phenolic block and make contact with the spring terminals that hold them into that block.

The contacts inside the horn have to make good contact with the bullet connectors. The contacts should be bright copper and tight. A little electrical grease will keep them from corroding.
