On my Toyota 3rz there is a coolant sensor on the back of the engine. I think it is the important one that signals the ECU. I have been working on the engine and removed the two prong connector to the sensor. Now I see the yellow plastic around the female pin connector is broken. I vacummed out the small broken pieces from the sensor part. The pins ore ok. I was going to put dielectric grease in there and just put ot back together. Or should I just put it back together as is? The yellow plastic used to extend out from the female pins, now it is just level with them, the rest btoke off. Brittle I guess. I don't want to make trouble for myself, I know there are pigtails that can be wired in, but getting the right one etc and then having to splice the wires is something I would rather not do. It is very hard to reach in the back there to work on it. I thought since there are actual professional mechanics here I could get an opinion. I suppose the full plastic is for a reason in the connector.
