I have a 2003 matrix xr, 5 speed, 1zzfe. I recently replaced my steering wheel with a whole nrg setup. Steering wheel, slim hub, and gen 2.8 quick release. My question is, how in the world do I wire my horn??? I need to know what to do for the horn to work when I hit the button on my wheel. Thank you!! I about got in an accident tonight and I had nothing to let the driver know he was coming over with me next to him
