So i purchased the wolo bad boy 419 horn with the built in compressor. my question is i had 2 horns before, with a total of 4 connectors, now i have the new horn which requires 12 volts and only 2 connectors. which 2 do i plug in? one set has extra wires and the other does not. the horn came with a relay but im not sure if i need that. heres the horn in question.




as you can see it only has the 2 terminals.

Thanks for any and all help,

Dave




p.s. i did a search and didnt come up with anything conclusive
