Actually there is no such item as hella relay. From what I know.

 

You can get a relay from Sim Lim Tower. Cheaper than Autobacs by at least half the amount. Not playing down Autobacs. My relays are from Autobacs. Their packaging are nicer, clean, comes with instruction (japs) and compact.

 

You just need to do a simple calculation to determine the type of relay needed. For example your horns consume 15amp so get a 20amp relay will be more than enough.

 

Relays are nothing more than an electrically operated switch.

 

You can read on this (good to read about "Pole and throw" section)

NOTE: Make sure you add in a fuse in between the horns and battery.
