Harborite88 Posted March 22, 2022 Share Posted March 22, 2022 Hey everybody, I’m redoing the dash on my 86 F350. Lots of added and no longer used wiring under there. I’ve come across a module that I can’t identify. Can you guys help me with that? Please and Thank You Link to comment Share on other sites More sharing options...
Gary Lewis Posted March 22, 2022 Share Posted March 22, 2022 The bottom/bigger thing is the speed control amplifier, and the top thing is your horn relay. I think you can unplug and remove the amplifier if you don't want the speed control, but your horn won't work w/o the relay. Link to comment Share on other sites More sharing options...
81f100custom Posted March 22, 2022 Share Posted March 22, 2022 Horn relay is the first thing I thought of when seeing it but have not done any research or looked in the EVTM. Should be able to find it in that someplace. Link to comment Share on other sites More sharing options...

I actually bought the printed version for Rocky off eBay but still refer to the one here most often because it's faster to find things, usually.

And the ability to right-click, grab the pic’s URL, and paste it in works so well. Link to comment Share on other sites More sharing options...
myrl883 Posted April 26, 2022 Share Posted April 26, 2022 I agree. And the ability to right-click, grab the pic’s URL, and paste it in works so well. Only trucks with speed control had horn relays. Link to comment Share on other sites More sharing options...
