Hey guys. Changed all 4 A/F sensors. I'm a diesel fleet tech, and spray our weather packs all the time to clean the grime with contact cleaner with no ill effects. Well the rubber Toyota used doesnt like contact cleaner it turns out! They swelled up, and will likely deteriorate over time so I'd like to replace them. What kind of connection are these? They dont appear to be Deutsch connections. Usually a kit can be bought with replacement seals for these sorts of connections. They are the orange ribbed seals.
