On my new NX200 I can see the small gauge wires going into the engine control module. I showed it to the Service Adviser at the Dealer and he said he doesn't design the cars. I think this is suppose to have some kind of a cover on it. Can some one look at there NX and tell me if there's looks like this.

Wow, I'm surprised just doesn't seem right. Thanks for looking. If nothing else I'm going seal it with silicone. I don't want any mositure or debri to get to the pins that plug into the engine control module.

I remember a discussion about the same thing on another forum about open connecters. The manufacturer stated that they were left open so water could drain through the connector. He explained that the air would dry the moisture if it was open but would corrode if it was not fully sealed, Not always possible on motorcycles.

I am surprised that Lexus did not put a cosmetic cover over this connector. I think that a majority of vehicle owners only open their hood to add windshield washer fluid if they can figure out how to open it. The only time that they have seen under the hood is at the dealers when the vehicle was delivered. Readers of this forum are not among this group.

That's what I was thinking that it should have a cosmetic/protector cover which at least would stop any kind of liquid from getting in there. It seems that if liquid was to get in there it would contain it and not let it drain.

I can just see the Lexus Technician walking up to the car with his cup of coffee when the hood is open, bumping into the car and spilling his coffee on the connector. Hey crazier things have happened!:eek:

Air dry. If its sealed in then it can just linger in there. That's the impression I am getting. I wouldn't mess with it, especially since if something does go wrong and you messed with it, it could void the warranty.

Valid point and adding to this, it might be worth it to ask someone that specializes in vehicle electrical system to get an opinion or some direction on what do here.

When Rowe Electronics came out with the PDM60 (a 60 amp electronic relay and fuse module) they had a 9 or 12 wire open socket on their pigtail. This is used in BMW motorcycles and riders complained about the open socket.
Rowe explained at that time that yes it would get wet but no harm would be done as the water would drain. They have since changed design to longer wires with no socket. This was done because of the tight spaces that are under the saddle.
To save electronics that get wet the first thing is to remove as much power as possible, Next try to shake out as much water as possible and safe then try to air dry. This is what open sockets do.
About the only thing that you could do is spray a water repellent on the socket but you may damage the socket and the wires.
Consider that Toyota would not have left this plug open if it would cause a problem. They may already have a water repellant solution that we do not know about and anything that we do will damage the current solution.
