jonathantennantbtinternet Posted December 28, 2019 Share Posted December 28, 2019 Maybe a odd subject title, but I have a ex Sigmax race car that has never had a horn fitted. I have the push button and 5 or 6 terminals . Would anyone be kind enough to let me know what terminals are used, I presume it's the purple and black wire on the wiring loom and the other wire goes to earth. Many thanks Jon Link to comment Share on other sites More sharing options...

I'd test it like that before any definitive wiring.Locate the fuse first, and I don't think that any Sigmas had horn relays from the factory...I think that you've already got a wiring diagram......I have the push button and 5 or 6 terminals .Could you add a photo of that? Do you know if it had controls or displays on the wheel for racing?Jonathan Link to comment Share on other sites More sharing options...
