Wiring harness sensor wires
im no wiring expert, but i have been playing with as much as i can to learn. from my understandign just like everything else, plugs can last forever as long as they arent abused and neglected. as long as theres no corrosion/melting they shoudl work totally fine. no need for new ones unless you melted tehm in a 1) fire 2) heat from something 3) fire 4) short that caused a fire or the car has like mad corrosion on all the electrical parts, even then its fixable, but short summary is unless its burned/melted leave it alone with plugs.
