I did take the time to read the Hella horn threads on this forum before posting. Because of the work I put into this, I thought it worthy of its own thread. What you see here is one set of Hella “Sharptones” and one set of Hella “Supertones”. I used aluminum “angle iron” and a rivet gun to fabricate the brackets. One of the relays provided by Hella was found defective and thrown away, the second relay worked fine for a while but eventually became suspect. I ordered a 75 amp Bosch/Tyco relay and it is working great. Prior to ordering the oversized relay, I did go to the Hella factory website and utilizing their data to compute total amperage draw, I found that one of the Hella relays should’ve been able to handle the current draw of all four horns. I used the voltage from the factory OEM horn lead to provide a signal voltage to the relay, all wiring was covered with conduit and a fused circuit is directly tied to the battery to provide current to the horn relay circuit to the horns. Legal disclaimer, I’m not a licensed electrician nor a car mechanic, follow all manufacturer’s instructions, your mileage may vary.
