I have wired in a horn button on/under dash and works GREAT...but I really would like the horn button on the steering wheel to work so....
I have read and believe I understand the Vw horn wiring but my steering wheel is where I am lost. My steering wheel is mounted to a cap (no holes in cap for a wire). The cap & steering wheel then slip onto the steering shaft. At this point the steering wheel & cap might as well be part of the steering shaft. This steering wheel and cap do not slide or brush up against anything in the turn signal area. I can connect the grounding wire up the steering shaft and onto the horn button however there is no way to get a wire back to the steering tube. Others must have my steering wheel and how are they making the horn work? Please see pictures
