Question about 1999 Pontiac Montana
Lots of wire connectors under the driver's seat
We have no wiring diagrams here-- as the experts
are at home & have to find those things on their own

I would disconnect the battery minus - cable first, ensure the airbag connectors are the same ! otherwise I do not think you have a problem !!

Hello and welcome to FixYa!
You will need to remove the seat to gain access to the wire. You can work freely with the seat off.
Hope this helps and thank you for using FixYa! Have a good one!

This is caused by a bad sending unit in the fuel tank, I have
seen this many times and a new fuel sender fixes these every time.
This is very common in montanas... also for the fuel gauge (I believe its applicable for a 2000 and later), it may be an issue with the C-305 connector.
Its a pass-thru connection for wiring (from inside cabin to outside/underneath). It connects various wires for things in rear of vehicle(including connection to fuel pump/sensor). While its weatherproof on bottom (underneath) it is not inside cabin, spills/ various leaks inside can cause water intrusion and subsequent corrosion of wires.
The connector should be under carpet to the rear of drivers seat (you may be able to see exactly where by looking under vehicle for a bundle of wires that come out from cabin) .
