just finishing up on wiring my challenger. The overhead console is left.Can someone help with the following:

Seat belt light- Where is the sensor....on the passenger side, drivers? I cant find anything associated with seatbelts.

Low fuel- is there a wire from the overhead console main harness(under dash) that goes to the gas gauge or a wire that leads to the tank?

Door ajar sensor were great.
Any help will be greatly appreciated...Thanks
