Horn relay

I need a new horn relay for my 86 F150 without cruise control. Advance Auto Parts only lists one with cruise. Does this matter???

I have no idea. I see rockauto.com shows a variety of 'em, might wanna look at 'em there. Maybe just take your old one to the auto parts store and match it up.

How many leads are hooked to the relay?

Model, year?

What makes you think it is bad and not wiring or the horn or the switch in the steering wheel?

My 1981 Ford Shop Manual says a relay is used only on vehicles with speed control. If I had my scanner readily available I'd scan & post the relevant parts, it's only 3 pages.

Yes, the schematic I have also says you do not have a horn relay, if you do not have cruise. The switch in the steering handles all the current for the horn with no relay.

I've got an after market steering wheel on it. The horn started to blow intermitently one day on my way to work. So I pulled over and unpluged the horns. I finally took a look at it today. Found a loose bolt under the horn cap. It holds the horn contact in place. I still don't have a horn. So I thought that maybe the contacts where stuck closed and this may of burnt out the horn relay.

Since I don't have one, I'll take another look at it.

Thanks
Mark
