Hello all,

I have a 1953 3100, and am putting it back together. I have a new wiring harness, but it doesn't show one item that is installed on my firewall. It is the black box on the bottom left side.

Item

I've looked in the shop manual, but don't find it.

From the pic, it seems that maybe it is going to the horns. Not sure...any ideas?

Thanks,
Steven
