Recently found a really nice set of dual horns for my 1978 CB750F SS. I thought it would be a relatively strightforward install to replace my horns which have never worked since I bought the bike in May. It seems that the PO did the Devil's own work on the wiring to the horn, and so I'm clueless excatly where the dual hookups attach. The "new" horns have two wires with covered butt-type connectors (one green, one black) which appear to go into into the headlight housing. The real culprit I suspect is eventually going to be that damned Ungo Box someone installed when they were in fashion in the early 80's. Looks like a nightmare to uninstall and may in fact affect my horn set-up.
Does anyone know the correct wiring for the dual horns for my bike? Thanks to any and all responders.
