I think the connectors used for horns are wider than battery terminals. I'll have to check, dont recall the exact size.[DOUBLEPOST=1534935924][/DOUBLEPOST]http://www.ferrulesdirect.com/electrical/OBQuickDisconnects.htm[DOUBLEPOST=1534936639][/DOUBLEPOST]I think the bigger horn connectors are 6.3mm and the smaller ones are 4.8mm
I was just pointing out the size difference, good automotive parts shops usually have both sizes.
