Reverse horn alarm
Does anyone know how to disable the horn alarm that the dealer installed on my truck that sounds when your door is open and you are in gear?

Sorry... that doesn't work... I cut the two wires on the seatbelt receiver and spliced them together because I was sick of the dinging when I didn't have my seatbelt on. Then when I got my U joint fixed at the dealer, they went ahead and put that fantastic little recall program on for me. It still honks... even with the seatbelt wires are spliced together.

I used a relay to open the circuit to the horn when the reverse lamps are on. The relay coil is energized by the reverse lamps. The common to normally closed points on the relay allow the horn to operate when not in reverse, and break the circuit in reverse....

The seatbelt jumperwire trick does not work, even with the seatbelt pluged in the thing still goes off everytime you put it in R

You need a Bosch/Tyco 30A SPDT relay - commonly available from AZ or CSK for "fog light" control. The terminals on the relay are numbered. Terminal 30 is connected to terminal 87A when the relay is not picked (de-energized). On my truck (2007) each horn has a ground wire on terminal 2 of the horn. Those wires are BK/DB and BK/OR. You have to break those two wires and connect the horn terminals (where the 2 wires went) to terminal 30 on the relay. Then connect the two wires (BK/DB and BK/OR) that were connected to the horn to terminal 87A on the relay. Terminal 85 on the relay is connected to ground. And terminal 86 is connected to the backup lamp circuit - I gotta find my note on that... OK the reverse light feed comes from the TIPM connector C8 pin 11 - a WH/LG wire. You can splice into that wire and connect it to pin 86 on the relay... you should be good to go.

This is on my 2007 CTD Ram and it looks like the 2006 is the same. Don't know for other years...
AND
If your not at home working on your vehicle electrical system, or don't understand the vehicle electrical system or relays... let someone who knows what their doing and has a "shop manual" with the wiring diagrams, do the work for you... so you don't cause any catastrophic vehicle failures!!!

That's essentially the same thing. Maybe the trucks that had the recall done on them it doesn't work on them, but the ones that come from the factory already "honked" up it works on. I wish mine would be as easy as yours to fix.
