The horn pull together under 20 amperes. In my car (Jeep Wrangler TJ) it so that the horn was possible anzuschliesen both directly to the original circuit. Is quick and easy with a good result for cheap money.
Why is there still only 4 stars?
Because certainly not all cars are designed in the horn circuit to 20 amps, the manufacturers have an extra guide and an extra relay attached to a dedicated circuit to build. Good thought along, but why in God's name nobody then thought of a fuse holder and a fuse? This would have only a few cents more cost ... So the inclined hobbyists must still going on and get additional parts somewhere in a hurry again. Please stop something really think it through, or inform the customer accordingly in advance!
