I've purchased a pair of horns I'd like to add on to my OEM horns on a 2002 Ford Ranger. I hooked a hot wire from one of the OEM horns and conntected to a "Y" connector. When I plug the wires into the add-on horns it only works if one add-on horn is hooked up. When I hook up the second horn, all the horns just click like there not enough juice to activate. Do I need to hook up an additional relay and if so, what's the procedure? Thanks

hi you need to add a relay.i would wire it to the factory trigger in the collumn which is yellow and green (-) at the collum be careful when testing they are run with the airbag wires.

pin 85 to yellow and green in collumn

pin 86 to 12 v

pin 30 to 12v

pin 87 to the additional horns

make sure and fuse your 12 volt connection

good luck
