Message: <blockquote data-quote="Zcat7" data-source="post: 646323" data-attributes="member: 14023">The old horn wiring challenge again... I'm trying to re-instate my steering horn push as I have a toggle on the dash at present. I have earth on the centre wire and both the column and tube are isolated from chassis earth, which is a good start. When I push the horn button it transfers earth to the column/steering wheel but it doesn't make it to the tube to send the earth, via the tag at the bottom, to the horn. What is the main "electrical" connection between the steering column and tube, is it this bearing?It's worth noting that I have an after-market steering wheel (some sort of 3 spoke Moto-Lita type thing) so no indicator cancelling and a cassette type horn push that sends the earth to the steering wheel.</blockquote>
