Marco Air Horn install question.


Recommended Posts

I am almost positive you need to use the relay or you can draw too much power on the wires. I would guess there is already a relay there, but is it good enough? Other smarter than I, will be along soon with better answers, I just wanted to give a quick, I wouldn't before you do and regret it. Good luck :happy34:

You need to run a hot wire from the battery through a relay. Use the factory wires to trip the relay.

 

So do you mean the factory horn wires?

I will be disconnecting the factory horn so should I be able to use them for power, correct?
