JordB110 0 Posted February 1, 2002 I want to put a mo-ped horn on one of my tractors(B-series). Any ideas how to hook it up? There are just two unmarked terminals on the back(of the horn). Thanks in advance, Jordan. Share this post Link to post Share on other sites
StinKy 0 Posted February 1, 2002 Get a switch (momentary button) from the auto parts store. Run 1 wire from the battery (+ terminal) to the switch. Then run another wire from the switch to the horn. Since the horn has 2 terminals, you may have to run another wire from the other terminal to ground. Just play around with it. At the worst, the horn may not be 12 volt and it will be real loud but won't last long. So then get another off a junk car. Share this post Link to post Share on other sites
