If you ever happen to have your plastics off you just want to take them off for this i strongly suggest using dielectric grease to prevent corrosion in the electrical system. Just find every electrical connection from the brake lamp to the EFI cpu and go to town.
This is a 3oz tube and costs roughly 10-15bucks. One is all you need.Dielectric is an effective barrier to moisture and protects electrical connections, ignition parts and wiring from moisture, salt, dirt and corrosion.
