Hey every one, I just got one of these horns, but I don't understand how the relay works? I have 4 pins but only two wires (+ and -) that connected to my old horn? I just plugged them straight in the 139db horn and it gave out a faint beep - about the same as my old horn, then I chucked it across my battery and it worked.
My volt meter checked that there are 12v going to the old horn so my guess is that it cant get the current to the new horn when just straight plugged in. Obviously the relay that came with it somehow fixes this? If you can do a basic drawing or somthing it would help alot (I learn from pictures or some shit).
Or just tell me (in detail) how you guys hooked this baby up.
Thanks
Rm
