Yousef Posted February 4, 2017 Report Share Posted February 4, 2017 Hi All, I've recently installed a new horn on my 620, and I've had to try and wire the thing to my steering wheel. The problem is that when I turn the wheel the wire will, of course, end up wrapping around the steering column. This causes wear and tear on the wire that I'd like to avoid. Any other methods that folks have used to get around this besides using an external button? Maybe someone could tell me how their horn wiring works on a stock 620. Thanks, Yousef Quote Link to comment
datzenmike Posted February 4, 2017 Report Share Posted February 4, 2017 The underside of the wheel has a circular brass ring. The steering column has a small spring loaded brass pin sticking up. When the wheel is fitted, the pin rubs the brass ring in any position the wheel is turned to keep in contact. The wheel transmits this through the horn button to ground to activate the horn relay.

Yousef Posted February 4, 2017 Author Report Share Posted February 4, 2017 So the wire isn't attached directly to the wheel, but instead contact is made through the pin touching ring? I bought a stock steering wheel on ebay (the one with the horn bar), so i'm assuming when you refer to the ring you're more or less just referring to the material on backside of the wheel. I don't have that pin setup, I'll have to look into that. Thank you for your description Mike. Quote Link to comment
datzenmike Posted February 4, 2017 Report Share Posted February 4, 2017 I would guess all steering wheel/horns are this way. This one is a contact on an arm lower right (I thought a pin but have had several Datsuns) my 620 had this kind. The arm is springy. Quote Link to comment
Yousef Posted February 4, 2017 Author Report Share Posted February 4, 2017 Great thank you so much for this. It looks like I do have the springy arm thing! I appreciate it, cheers. Quote Link to comment
