QuestionI have an '01 Camry. I replaced the original single horn to a dual Italian model using the single wire for both high & low horns. I noticed that I am blowing the horn fuse regularly. The new horn came with a relay which I did not use and no instructions. The relay has connector in one end with markings which are "greek" to me: The markings on the connectors are 85, 86, 87, 88 & 30. It also says 12V 30A. I assume I have to use this relay to avoid blowing the fuse. Help please!
AnswerYes you do need to use the relay, the horn is drawing too much current through the existing wiring causing the fuse to blow.
You will need some wire and connectors, hook the relay up as follows:
Connect the #30 terminal with 12gauge wire directly to the battery positive post.
#85 to the existing horn wire(either high or low)
#87 to the horn connector
#86 to body ground(ignore the 88 connector)
The horn is now able to draw current directly from the battery when activated, not through the horn fuse.
