Curious - do you ever use the max defrost button that we are replacing? I have never used it, and there is a button in the main screen that is just as easy to hit. Easier in fact.
Things are different here. I think I’ve used the max defrost once. I used the screen button. It’s very temperate here, although humid, and the automatic system works well without freezing you.
Thanks to you, @markboris, and @i8iridium I was able to do this too. I purchased the light cluster with Liftgate button on eBay (I presume it was from a wreck), and followed your and Mark's very helpful posts. On the driver side, I ran my wire under the dash in a rubber cable channel at the junction between the under dash trim piece and the footwell. So the wire didn't need to go under the carpet. I wrapped with electrical tape anywhere that I thought might wear, as well as taped the wire in areas that I thought might either wear or rattle. And like you, I just stuck the wire into the back of the connector, though I did bend the wire into a zig-zag in order to create higher pressure contact points with the pin of the connector, and then taped the wire to the rest of the harness. Hopefully that will work for the long term, though if you find the right pin size, I'd love to know!
Thanks, but I'm kinda slow at the stuff - and working on the street is less than ideal!Awesome John, glad it all worked out for you. However, now that you have done it, I bet it would only take you an hour to do it again!
Yes, I am serious! I am in the process of mounting on on my Tiffin Motorhome for the same reason. My theory is that the passenger horn button is a more effective solution because it should eliminate the passenger yelling and causing a driver distraction. The horn sound would alert the other driver and reduce the likelihood of an accident happening. I am open to any opinions, but my theory comes from both flying & driving with passengers that often see things before operator.
Alright Eric, if you want a second horn button, here is how to do it:
There is no way I am giving my passenger, primarily my wife, horn control capability. First of all, whomever she honks at will think it is me honking. And I might not agree with the honk. And secondly, if I am driving, I am in control of the honk. Period.Alright Eric, if you want a second horn button, here is how to do it:
You need to tap into a Green/White wire at C2280D connector in the BCM (Body Control Module).
The BCM is located behind a panel where the front passengers feet are. To remove that panel, you first have to remove the under dash panel which has two clips. Pull it down and out then grab the plastic panel over the BCM and pull it straight out. The C2280D connector is the large one on the bottom. Carefully remove about 2" of the black cloth wrap that is around the wires and find the Green/White wire (Green with very very thin White stripe).
Here is the tricky part, there are TWO of those colored wires in this connector. The one you want is slightly thinner than the other. Attach a wire to the Green/White wire (however you want to do that) and short it to ground. The horn should work as soon as you do this. If it doesn't, you have the wrong wire so connect it to the other one. You won't mess up anything if you short the wrong wire to ground. Then of course all you need to do is install a momentary switch wherever you want, and run the wire from the Green/White wire to one side of the switch and a ground wire to the other side.
I have verified this works (like I do all mods I post) so have at it and let us know how it turns out.
I have orientated the photo below how the BCM looks when you remove the panel. Again, it is the bottom connector C2280D.
I had to use the same color as went into the BCM.
Great work! Too bad about the panel. I am still procrastinating - I have had the switch for a couple months now. And then there might be a fix for the switch assembly that stops the lights on bug, which I guess means those of us who actually do the mod won't get Ford to pay for the updated switch.OK, procrastination over with:
I busted three of the retaining posts for the driver’s side panel, so don’t be like me:
I bought a big roll of brown wire and used like 6 or so feet of it.
I am hanging on to the defroster switch and will swap it back in if I ever get a headlight switch recall notice.
