Hella Sharptone horns with relay

ZStalker505

Finally got around to messing with these horns. Supposedly yhe stick horns are already on a relay so plugged in the signal wires to the right spade of you're looking at the back of the hella horn and black ground wire to the left spade. Annnnd they barley put out noise worse than stock. So guessing they need the relay wired to battery but can't seem to find a definitive on how to wire the relay..m it's either pin 85 is+ 86- or vise versa. Depends on if steering wheel horn switch is connected negatively or positively.
