How To Permanently Silence Your Jeep's Seatbelt Chime


Okay, let's get the liability stuff out of the way right up front. This mod will make your Jeep's computer think your seatbelt is fastened even when it isn't. This has important implications for how and when it will deploy the airbags, which in turn has important implications for the condition of your face and other important body parts in the event of a collision. DON'T DO THIS mod if you're trying to silence the chime for the purpose of driving without your seatbelt on. This mod is ONLY for people who wear their seatbelt but get annoyed by the reminder chime going off before they've had a chance to put it on. I'm not responsible for anything bad that happens to you or your Jeep as a result of this modification. Now, with that out of the way, let's get started.

I always wear my seatbelt, but it bugs me that my Jeep feels the need to remind me to put it on every time I start it. It does this by sounding five obnoxiously loud chimes as soon as I turn the key to the ON position. Out of habit, I always start the engine first, then put on my seatbelt, not the other way around. It's a habit that developed over 25+ years of driving, and it's not going to change now just because my Jeep says so. When I start my Jeep, it yells at me to put my seatbelt on, and I hate that. So I fixed it. Here's how you can too.

Under the drivers seat, near the back, you'll find a black connector with 4 wires connected to it. Stay away from the yellow connector! That one is for the airbag sensors, and you don't want to mess with it. In the black connector, locate the green/white striped wire and the black wire. The black wire is your ground. The green and white wire is the seatbelt sensor - it tells the computer when your seatbelt is fastened. Cut the green and white wire, and tie it into the black one. That's all there is to it.

All this does is fool the computer into thinking your seatbelt is always fastened. As noted above in the legal disclaimer, that's really bad if your seatbelt isn't actually fastened, because your airbags will deploy differently depending on whether or not it thinks you're wearing a seatbelt. If you are, then it doesn't matter because the computer will behave exactly as it should; if you're not, the computer will behave as if you are, and that could be bad. So wear your seatbelt, and don't blame me if something bad happens because you didn't.

Now those annoying chimes won't go blaring in your ears every time you start your Jeep. Enjoy the peace and quiet.
