Kansas_City_Milkman Posted May 11, 2011 Share Posted May 11, 2011 I've recently bought one of these old fashioned "ooga" horns and am in the process of fitting it to my Stag.I want to keep the existing horn in place.I already had a Moto Lita steering wheel so have just ordered a push button horn switch to go on the steering wheel so I can operate the "ooga".I've gone for a relay but I'm not 100% certain how to wire up the switch.Based on the attached diagram I assume I take a wire from terminal 85 to the horn switch - this then grounds with the steering column when pressed. I then take a live from the ignition and run this to terminal 86 on the relay. Should I stick another inline fuse in this wire to be on the safe side?Any help greatly appreciated.

stagnant Posted May 12, 2011 Share Posted May 12, 2011 If you're using the relay type as in your diagram, you've got 2 options:Substitute item marked 'switch' for your horn push, orDispense with the item marked 'switch' and put the horn button into circuit between terminal 85 and ground. You don't need another fuse on the supply to terminal 86 as this will be protected by an existing fuse, assuming you take the supply off the ignition switch or ignition controlled circuit.
