i guess what i had was a three wire since it had the one red wire and two other leads that "plugged" into it. however, the new one just takes the red lead. that red lead runs from the battery... to the regulator, where the other two leads start. from there; all 3 of those go to the horn relay and onto the alternator. the short question is: can i run the red power lead from the battery directly to the horn relay and along to the alternator; cutting out the regulator and its two leads and have the horn and everything still work?!?
