Looks like this is the most appropriate forum to post my question.

I just bought a new pair of electric airhorns. And this is the first time installing horns for me. On the instruction sheet it has the horn wired up to a relay. Will i have to buy an aftermarket relay such as a bosch one and add it to the existing horn circuit or will the factory horn relay be enough?

Cliffnotes:
Installing new airhorns
Add extra relay or just connect up the new horns to the circuit?

Cheers

 

Bump

Well i'll definately completely remove the factory horn. So are you suggesting just unplugging the old one and plugging the new pair in parallel or series? Because my new horns are a set of 2 individual electric horns one 510hz and the other 410hz. If i was to run them both would i need to add another relay additional to the factory one?

Appreciate your help man. I will install them when i have time.

Thanks
