Have the truck listed above regular cab. Swapped both seats to bucket seats from like a 2004 or 2005 Silverado! Both seats connected just fine but on passenger side seat ended up missing one 2-wire plug I believe it's pink and brown wires. And airbag light is now on. Something about passenger presence OBD code. Anyway to bypass or what am I missing?

Let's take a step back and start with the actual code that you are getting. If this is the airbag squib connector then clearly we need to address that or the airbag system won't work correctly. More then likely your old seats had headrest and or side seat bolsters. Get a picture of the connector that is not plugged in and send over the actual code that you are getting and we can go from there. Thanks

Okay, the actual code I am getting is B0098 (passenger presence system configuration error)! Posting picture of connectors and seat sticker!

Just so I have this straight. You put these other seats in and this connector does not have a place to be plugged in?

If this is correct then unfortunately you are going to have to either change the passenger seat again to one that has the passenger presence system or the system is not going to operate and the airbag light will stay on.

I attached the info about this system but in short it senses when someone is sitting in the seat and it turns the airbags on and back off when they are not in the seat. The code is setting because it is running a self test to turn the light on and off but it is not able to due to it being unplugged.

Unfortunately the truck that you got the seat from was not equipped with this system so it doesn't have the connector. There is no way to bypass this because it needs to successfully turn the light on and off.

Sorry I don't have better news for you. Let me know if you have questions. Thanks

I have a 2004 Silverado. Someone cut the wires under the passenger seat. The seats had been replaced with ones with no wiring. I bought a set of seats from a 2003 Silverado. I took the floor connector also from the same 2003 Silverado but the cut wires on my truck from the floor have two dark blue wires does it matter which dark blue wire on the connector that I wire them to? I have already replaced the two-wire connector that had the same color code.

I assume you are talking about the electric seat circuits.

If so, you are looking at motor control wires and they do matter which ones they connect to so that when you press the switch, the motor responds in the direction that you are pressing.

They will still work but it will go in the opposite direction if they are installed backwards.

Please see the diagram below for the seat wiring.

Let me know what other questions you have on this. Thanks

Thank you. The seats I removed had no power and no wiring. The seat on the passenger side I am trying to install has no power either but has the connector. My concern is the passenger presence sensor. The truck is completely manual, crank windows, no remote unlock, etc. If that helps. If I can get this one right, I can go ahead and try to install the driver seat which is power.

Okay. I see that I did not attach the wiring diagram like I said I did. Sorry about that.

Just to be clear, you are just trying to get the seat occupation sensor connected and not any of the power options?

If this is correct, then you need the second attached wiring diagram below.

I show that you have 3 wires for this sensor as it is a typical 3 wire sensor. This means you have 5 volts supplied to the sensor and then you have what is called a signal and ground (low ref) wires.

Basically the 5 volts is supplied to the sensor and then the signal wire is what tells the module if there is someone in it. Then the low ref is just a ground wire for the circuit.

If you only have 2 wires, then I suspect this is for something else. Plus, I don't show them being blue wires, so I am thinking that this seat came out of a vehicle that does not have a seat sensor or you have the wrong connector for this system.

Let me know if I am not understanding. If not, can you get some pictures of what you are dealing with and that should help?

Thanks

I will take careful pictures, document the vehicle used as a donor and any other details I can think of. The connector for the Driver seat does look different as it only has the three wires. I will take further pictures. Thank you.

Okay. Sounds good. I suspect that they included the seat sensor in this connector if there is only one and there is no connector with just three wires. Or there is another connector further up closer to the cushion. If you can get the VIN of the truck that this seat came out of then we will have a better chance of figuring this out.

We will wait to hear back. Thanks for the update.

Rechecked the passenger side. Idiot mistake, the connector was not properly seated. Now the "air bag off" light comes on, on the mirror, and turns to "air bag on" when I sit in the seat. Now I need to move on to the driver seat. I put in a power seat from a 2004 Avalanche. I removed the hot wires to the seat and provided a ground and hot. The seat works but even though the three wire connector to the body side is present when connecting to the seat, the seat belt light stays on. Do you have any idea what wires from the seat would match the three wires from the truck side? I am not trying to get heat or memory working on the seat.

Okay. We are going to have to get a new post started for that because this one is titled passenger side so other people will not find driver side seat info under this if they are looking for it.

I am going to attach the wiring diagram below, but you have a switch inside the buckle that tells the airbag module if the seat belt is connector or not.

If you need more info on this, here is a link to getting a new post started and we can figure out the detail on this.
