The klaxon replacement horn, are a few decibels louder than the stock horn.
To make them fit you have to do a rigged install as they are two wire horns
and the stock horn is a one wire. You basically splice in two connectors,
and loop the ground to the horn bracket, the horn bracket which also has to
be made. Ever hear a Buick Roadmaster or a Cadillac fleetwood? They have 4
horns. I have the two extra horns on the R/H side. I pulled from a
fleetwood, I still never installed them.
